fteqw/engine/qclib/pr_exec.c
Spoike 577419de37 improve handling of writing to world entity.
split left and right alt. binds+gamecode still use left-alt exclusively. alt-for-red-chars only works with left alt. right alt is alt-gr, so text input now works fine.
fixed support for keypad and text entry.
sdl2 clipboard support, if we're compiled with sdl2.
fixed issues with sdl sound. shouldn't be so terrible now.
soundinfo command now more verbose.
support for interpolated ramps.
removed input line length limitations, although some limitations still remain.
