Fixing transforms for angle and alpha in FlxSpriteGroup to keep properties of children relative to the parent group
Linux64 build was segfaulting with the following error: "Program received signal SIGFPE, Arithmetic exception. 0x000000000047f352 in hx::Mod (inLHS=0, inRHS=0) at /usr/lib/haxe/lib/hxcpp/3,0,2//include/hx/Operators.h:93"
fixes #651: if you destroy() a FlxObject, set the exists flag to false
Negative offsets, and minimum positions were not calculated correctly
Fixing transforms for angle and alpha in FlxSpriteGroup to keep properties of children relative to the parent group
Merge branch 'dev' of https://github.com/grayhaze/flixel into dev
Removing unnessesary checks for skipping transforms
Merge pull request #648 from grayhaze/dev

FlxSpriteGroup fixes
removing isStatic property from FlxText
Fixed issue where animation would be marked "finished" as soon as last frame of animation was activated (animation should wait until last frame finished before being marked as finished).
Adding test script that runs "flixel-tools testdemos" command, so we can know if changes broke the build.
