	* Added support to get_folders call in the local folder account to filter by query
	* Removed get_folders_async from the local folder account because it makes no sense to redefine it to just call the parent
	* Redefined the create_folder method in the local folder account in order not to allow to create folders with the same name than the extra folders
	* Removed some invalid string comparisons in the guess_folder_type_from_name
	* Now Modest do not allow to create a folder called outbox, nor to move another one with that name to the local folders account
