Reverted "Delete Item" action to the way it worked in DB2.
Added "Dissolve Item" action, which works the way "Delete Item" worked in previous revisions of GZDB.

Draw Settings panel: upper/lower texture overrides can now be used.
Draw Settings panel: added 2 sets of buttons, which allow to quickly set or clear textures in current selection.
Things are now rendered behind AND on top of the grid/linedefs/vertices when they are dragged.
Redesigned hints system. They are now shown in a side panel.
Edit area auto-focusing is now disabled when script editor is open.

Classic modes: "Paint Selection" and "Toggle Full Brightness" actions can now be used from any plugin.
Fixed possible crash in DECORATE actor color override logic.
UDMF map parser should work ~35% faster now.
Texture browser form: keyboard focus was not updated when switching between textures using Tab key.

Various cosmetic changes here and there.
Info panel was not updated after leaving Visual mode.

Visual mode: dynamic light animation was not working.
Minor performance improvements in Actor, Configuration, UDMF and TEXTURES parsers.
Sector and Thing Info panels: fixed possible crash when trying to show unknown thing/sector flag.
Hints were not shown properly when multiselection was started while highlighting a map element.
Copy/Paste actions work much faster now.
Classic modes: rendered grid size in now adjusted to current zoom level.
Increased performance when canceling Edit mode after pasting.
"Export to Wavefront .obj" function: current selection is now converted to sectors before running the function (previously it would export selected sectors when there were sectors selected, or the whole map when no sectors were selected).
Sectors mode: optimized sector highlight rendering logic.
Sectors mode: optimized sector effect/tag labels update logic.
Geometry tools: optimized several core functions.
Hints for current editing mode can now be displayed when nothing is highlighted (currently the hints are shown only in Draw Geometry mode).
GZDB is now build with LARGEADDRESSAWARE flag, which increases amount of RAM GZDB can use from 1.4 to 2.8 GB.
These changes were made in previous commit. I just forgot to write info about them:
Classic modes: going to Draw modes when Edit button is pressed when nothing is highlighted can be disabled in Preferences -> Editing -> "Start drawing when Edit pressed over empty space in Classic modes".
Classic modes: removed Preferences -> Editing -> "Try to align horizontal tex. offset of dragged geometry", because it was more confusing than helpful...
Visual mode: changed "Move Texture Left/Right/Up/Down by 8" actions to "Move Texture Left/Right/Up/Down by cur. grid size"
Visual mode: holding Ctrl-Shift while dragging texture with the mouse will snap texture offsets to current grid size.
Classic modes: interiors of highlighted sectors are now highlighted when the action target of currently highlighted map element is sector.
Unhandeled exceptions infos are now written to the event log.
Angle control (the newer, photoshop-like one): left-clicking inside the control now clamps angle to 45-degree increments. Right-clicking inside the control sets precise angle.
Thing Edit Form: replaced angle control with newer one.
Classic modes: fixed minor rendering artifacts when drawing thing direction arrow.
Sectors mode: event lines were not rendered for things targeting highlighted sector.
Added "DropItem" and "CheckFlag" definitions to ACS and DECORATE script configurations.
Fixed a possible crash when rendering thing arrows in classic modes caused by incorrect vertex buffer size calculation.
Reverted changes to texture\flat access when "mixtexturesflats" option is set to true in game configuration.
Location and active tab of all Edit Forms are now stored while GZDB is running.
Focus management between editing window and the rest of the interface should work better now.
Tag Explorer plugin: editing window was not updated properly when Edit forms were opened from Tag Explorer.
Tag Explorer plugin, UDMF: comment editing was incorrectly initialized in some cases.
Plugins: fixed a crash caused by inability to find referenced assembly when loading a plugin, which depends on other plugin(s).
Undo-redo, UDMF: undo information was not created properly for several types of UDMF fields for the last map element in the selection when the selection contained more that 1 element.
Updated documentation.
Maintenance stuff:
Core/Plugins/Plug: made current display location and size information properly available to plugins.
Made Core/Controls/ColorControl available to be used by plugins.
Classic modes: event lines are drawn once again while panning the view (I've disabled this a while ago trying to fix performance problems in Classic modes).
