Test patch: enable moving folders between different parent folders in demo ui

[Jose Dapena Paz <jdapena igalia com>]

	Hi,

	This is a patch for testing purpose that allows moving a folder to a
different parent using "rename/remove folder" contextual menu option in
folders view.

	It works this way:
	* If you only put a name, it's the new name of the folder. No more than
this.
	* If you put "/a/b/c" it will move the folder to folder b under folder
(which is root account), and rename it to "c".
	* If you put "../b" it will move the folder to be under the parent of
its current parent, and rename it to "b".

	This should help to check bugs caused by moving a folder to a different
parent of the same account, and then trying to open it.

	Just, if you want to test the issue moving folders have a rich folder
tree, with many messages in the folder you want to test moving. And just
move it to a different parent in the same account. And then, when the
folder is visible, take your time to open it and you'll see the crash.
