RommPS's interface sounds (assets/rommps/sounds)

Sound effects from Konami's Metal Gear Solid series, (c) Konami Digital
Entertainment. Supplied by RommPS's author, s0liton, who uses them with
Konami's permission under its creative artists programme, in a
non-commercial title. They are not covered by RommPS's own licence and may
not be reused apart from it.

The cursor, select, tab, switch and setting sounds are mgs1-menu-move;
the rest come from the first set supplied.

Changes: converted from MP3 to 48 kHz 16-bit PCM WAV, one file per interface
cue (the same sound under several cue names where it serves several).
