* Improved layout of addons menu.
* Disabled input for 5 tics after a console-touching enter key command on the menu, so that weird stuff doesn't happen.
* Added Add-on options.
* cv_addons_option - chooses save location. A little smaller in scope than the weird Default/HOME/SRB2/Custom thing for screenshots - now it's SRB2 Folder and Custom.
* cv_addons_folder - goes with Custom for above.
* cv_addons_md5 - chooses whether to identify files on the addons menu with name comparison only, or with checksum comparison as well (more intensive hence not default).
* cv_addons_showall - chooses whether to show just supported file extensions, or all
* Some minor other refactors.
Bad:
* Screenshot options menu crashes on access for some reason (to do with itemOn not being valid?????) looking into
Used instead of pLocalPalette when attempting to determine objective truths, such as "the colours of this gif without color profile modification" and "what indicies should this colormap remap to".
Also, made f_wipe.c's paldiv only get calculated once.
Also updated any relevant project files that I can think of to include the new files, as well as the makefile of course. Some of the other project files haven't been touched in years so I'll leave those alone ...unless someone objects
Also makes comptime.bat work with git if able.
Development builds will now show the branch and the SHA1 hash of the revision. Also been tested to work with subversion, where it displays "Subversion r####". You know, just in case.
