FlxTilemap.loadMap() doesn't initialize widthInTiles

Issue #197 by: GregoryWeir

FlxTilemap.loadMap() doesn't initialize widthInTiles, but expects it to be zero. It only updates widthInTiles based on the provided map if widthInTiles is 0, which means that loading a new map into an already-initialized FlxTilemap does not change the width of the map.

I suggest that loadMap() set widthInTiles to 0 near where it sets the value of heightInTiles, which will allow the later while loop to properly set the tilemap's new width.

On further experimentation, it seems that _buffers also needs to be reinitialized to a new empty array in order to make loadMap work on a second call.
