Merge pull request #4 from azrafe7/master

Removed unneeded #if's
Removed 'Factory' preface.
Changed package to 'hxDaedalus' for consistency with project name.  Considered changing project to "Daedalus" but this would be impossible to google for.
Moved GraphEdge and EdgeData out of Potrace, as they are used in non-flash specific places and so are better separate.
DemoBitmapPathfinding:
 - back to UInt in RandGenerator (waiting for response on haxe issue #3552)
 - html5 bitmap loading delegated to openfl
 - couple of _assert_ added
