fixes #5
transformation history was shared by all users and kept growing as it
was never truely reset. Every time a user
used a banner a white background was dumped on top of the
stack making it possible to crash the server through an
overflow to core.serialize() function.
* minimize metadata size
also changed banners.max_transformations to
banners.max_undo_levels and lowered the value substantially.
* add versioning
* add recoverable per player history with saved colour
* rename update_all -> update_preview_inv
since it isn't updating everything, only
the preview and the inventory item
* dynamically update masks
to reflect the currently selected colour.
