first import with untested, but seemingly working particle system
several changes!

changed default smoothing to none (should've done it at the beginning)
fixed some bugs regarding clamping
added config texture path support if not overridden
added burst capability to populate (with range)
added clearing / explosion of matched tiles
added collapsing tiles, should be fairly robust
a very rudimentary version is playable
added swap verification and better UX, switched to custom juggler
added board bounds clipping
added "clearing" state for tiles (shaking to explode effect)
added explosion and shaking sounds
changed so tile explosions are more sequential and consistent
added momentum (only appears in sound pitch for now)
added screen shake and tile swap as a state and animation
added tile move sound
added scrolling tiled background based on momentum
better tile type system with more tile styles
added sequence matching for LOOMSDK
added multiplier and score display (rough)
made explosion a bit quieter
added possible swap search (no possible swaps = no moves left)
Adding support for saving to iOS photo library
added game screens, config, skin, removed some cruft
added starting with no matching tiles
more layout changes + quit screen
switched from simplelabel to label in gameview
Android saveToPhotoLibrary functionality
Updating iOS saveToPhotoLibrary functionality to return asset url
added end screen, betterized intro screen, added ending explosion, added some more transitional tweens
minor tweaks + adview (with fake ad)
fixed switched end view labels and possibly fixed some shaking sounds being stuck
