Updater 0.14

+ Added new Replacer tool.
* Replacer tool can have per-tool reach, blocks, nools of surface
checking and edge checking.
+ Toolbox menu is operational, however a better way of automatically
generating it may be possible.  Making menu items is extremely tedious
and lengthy.
+ Added the undo command's functionality.
+ Added new smart-undo to the undo's default command.  It will not have
a edge check of 2 seconds between different actions and undo a chunk of
them that meet this.  This mimics how some word processors handle undos.
> May need to redesign how the replacer tool functions
> May need to do some code clean up, especially with the toolbox
