[Bugfix] Renaming a list pushes the list to the end, instead of maintaining the position.
Adding new lists and updating every tab now seems to work. Introduced GLOBAL.msgIgnoreOnce variable.
Deleting lists and updating tabs seems to work now. Except for a weird quotation marks bug.
Removed strToValid(), not working with IDs anymore. Added lists now show in context menu, no page reload needed.
