What changed in EDuke32, build by build

Move Mapster32 autoexec to before the map specified on the command line is loaded, to allow EVENT_PRELOADMAP and EVENT_LOADMAP to work when loading a map from the command line. This makes the console output of autoexec a little worse but the OSD will be fixed at a later time.

Handle the save and savenn commands after the full tic is processed, instead of in the middle of it during execution. DONT_BUILD.

Don't cut off a row and/or column of texels when drawing floor-aligned sprites with odd dimensions.

Add new tint flag 256, which always skips hightile when picking an image source.

Explicitly opt out of hicfindsubst falling back to pal 0 instead of checking against the reserved palnum range.

Factor out hictinting array accesses.

Create a new struct for hictinting that uses a uint16_t for flags.r

Only allocate space for tint flags combinations that require a pre-computed texture to be stored in memory, instead of space for every combination.

Make menutext use MF_Redfont fields.

Optimize all menutext calls.

Eliminate the RedfontGreen type and replace it with indentations (like "Apply Changes").

Eliminate the RedfontBlue type and replace it with the Disabled or LookDisabled flags.

Add a new MenuEntryFlag to make an option appear disabled but still work.

Namespace all MenuEntryFlags_t.

Move cursorPosition and cursorScale from MenuEntryFormat_t to MenuFont_t.

Fix memory leaks in audiolib. Fixes issue #59.

Fix some indentation of the menu system.

Factor some menu code.

Scale menu spacers by font zoom.

Attach fonts to spacer menu entries.

Apply MenuFont_t.zoom to margins and indentations.

Add zoom field to MenuFont_t.

Shrink the MenuFont_t struct.

Touch up some menu options.

Center the episode menu vertically like the skill menu.

Clean up episodes, skills, and game modes in standalone builds.

Clean up warnings in standalone mode.

Clean up gamefuncs in standalone mode.

Don't print any warnings to the log if an unrecognized gamefunc is dispatched; this is expected and normal when they are renamed.

Add undefinegamefunc.

Remove an old hack from my menu system that upon closer inspection is no longer needed.

Change the way gamefuncs are handled to support and ignore entries named as the empty string.

Don't store redundant copies of default gamefunc names, since the indices are all that matter.

Disable G_FadeLoad because it doesn't work in any renderer and only causes glitches.

Keep music playing without interruption during map or hubmap transitions if the same file will be playing before and after.

Update LZ4 to 1.7.5.

Better support for working with blend in the editor

Get MSVC building again, DONT_BUILD.
