lawnjelly 6a31048dbc Tilemap editor - prevent changing tool when mouse buttons pressed 
Changing tool when painting prevented the corresponding commit of undo action when the mouse button was released. This led to undo actions getting out of sync and the undo system breaking the editor.

This PR simply prevents changing tool while mouse buttons are pressed, and prevents the above scenario.
