Editor tools with TileMap in Editor

[hunterbk]

When you select a TileMap node and have the TileMap (not TileSet) tab open at the bottom of the editor, it should lock your ability to use the scale/move/rotate tools until you leave that tab. Very often the Scale tool gets selected for me, and as I try to paint some tiles into the TileMap, the Scale tool takes priority over the TileMap brush and scales up the TileMap node.
