Mystic Knight Maya - alpha 0.2a

+ Added the animations for internal views that were missing: 
	-> Beach: Starfish and Coral.
	-> Forest: Isobora, Spitting Plant and Forest Boss.
	-> City: Lizardmen.
	-> Now all enemies currently in the game have some form of "internal view". New enemies will always be added with them as well.
	-> Internal views differ for each enemy: some show internal organs, others show an external close-up and others toggle on/off layers of the sprites.
	
+ Added the initial pass of Maya's voices to the game:
	-> All ero scenes are now voiced.
	-> Voice volume can be adjusted in the options screen. The default value for the slider is 90% of the max.
	-> Variations of voices include: hurt/pain grunts, fainted screams, erotic moans that change based on scene speed and roughness, climax, blowjob and oral slurps, gagged and muffled sounds, etc.
	
* Enemies that have more than 1 ero scene now always switch between each scene for subsequent grabs (instead of being random chance).
* Fixed Maya's fainted scream being repeated during vore scenes.
* Forest Boss vore animation: added spores being released during the initial grab.
* Fine-tunned Maya's physycs interactions with some game objects: barrels, boxes, passable platforms and ladders.
* Batgirls are a bit more agressive now, and chase Maya more often when she's naked and/or fainted.
* Other minor/undocumented fixes and changes.
