* use a different subfolder for each IWAD's saves.
* do not allow load and save CCMDs to escape the save folder. Absolute paths and '..' are being blocked now.
* unified savegame path and filename generation in one single function. All ad-hoc file name generation was replaced.
* -loadgame will also use the designated savegame folder now.
* these circumvented all internal texture replacement logic. Texture objects should only be resolved right before drawing them
* added an explicit ‚tilebackground‘ option for the summary screen to fix problems with bad decision logic based on incorrect texture type checks. Automatic tiling no longer depends on texture type, but solely on size.
* added a DrawTexture variant that can be passed a texture ID instead of a pointer
* it is now possible to switch back to the main intro loop from the fullscreen console.
* do not distort the background of the fullscreen console. Always draw the console on top of what the main loop currently displays with a translucent black overlay.
* do not use the CONPIC for the fullscreen console as it tends to be more of a distraction than an asset when filling the entire screen.
* cleaned up c_console.cpp and moved several pieces of code unrelated to actual console management out of it.

* Simplified some stuff, made up-to-date
* Dealt with DST problems
* Made SystemTime.Format clearscope, as there is no reason for this function to be limited to the ui
* change the license of the main file because there is no more id-based code here licensed under the GPL.
* moved VM interface definition out of the implementation.
* moved idmus CCMD out of implementation because it is dependent on Doom level definitions.
* moved s_music.cpp into the music folder with the rest of the music code.
