load tiles using framework-legacy-sprite from coronalabs

Slight tweaks toward getting Tutorial-00 working the latest lime and Corona SDK
started converting Tile and TileSet to use graphics.imageSheet instead of spriteSheet

works for simple tileset case like in tutorial-00

need to fix the animated tile cages
Tile properties added to the tileset are attached to the the specified tile in the layer
noticed that the tileset properties are applied when the tile is :created not on :new
fixed issue with graphics.newImageSheet automatically handling scaled image selection
simple tile animation
removing dependency on sprite.lua

the only thing I do not understand yet is loading tile animation from a data file
fixed regex for checking tileset path in tileSets
added a cancelled event to ui.button

fixes the bug in the lime tutorial-10 where if you touch and move on a direction button the guy is stuck moving in that direction
support either startFrame or start in sequenceData on an animated tile
removed debug print call
replaces usage of xReference/yReference with anchorX/anchorY
using imagesheet the old HDSource fixes are unnecessary
Merge pull request #11 from anthonymoralez/master

Updated for new Corona ImageSheets plus tons of fixes. Nice!
