Added, Textures Browser: redesigned textures list. Textures preview size can now be changed from the Textures Browser window. Folders are now shown in the textures list.

Fixed, Script Editor: Find and Replace window now sets keyboard focus to the input textbox when opening the window/switching between tabs.
Fixed, Nodes Viewer mode: SEGS overflows were not handled, causing a crash. Also extended SEGS limit is now used.
Updated ZDoom_DECORATE.cfg (A_SetSize).
