Tile names

When you add a room, any new tiles created will be named "roomname n"- i.e. if you create a room named Bedroom with 5 new tiles, they will be named "Bedroom 1" to "Bedroom 5". This should make it easier to find tiles in the editor, especially now that bitsy has a tile name search function.

Thanks to Von Bednar and Em for this feature suggestion.

Apologies for the lack of updates recently; I've been completely refactoring image-to-bitsy and it's taking a while. But I thought it's worth coming back and adding some useful features to the current live version. Wish me luck!

Kisses,
Max
