mikmod: Upgrade mikmod core from v3.2.0 to v3.3.11

Browse source 
* Get rid of the non-functional GT2 loader
 * Add the UMX loader
 * Add HQ mixer routines (and make it configurable)
 * Allow samplerate to be configured at run/playtime
 * Support >64KHz mixing/playback
 * Correctly restore non-boost status

(The diff to upstream is much smaller now too!)
