The macro defined namespaces confused the hell out of lupdate and more or less broke translations permanently. Looks like the only way we can do it is to have a hardcoded namespace, which goes against my instinct, but honestly how likely is it that we'll change the namespace anyway (I guess forks might want to do it, but that's their problem ;) )
While good in theory, a WYSIWYG rich text editor for large video frames
was unwieldy (and in many cases unhelpful). Instead the titler will
show plain text/HTML tags so the user can still write rich text but
without the unwieldy UI.
For a true WYSIWYG experience, we would probably need to write a true
graphical editor (a la Premiere's titler), but that's a later goal.
This titler will be sufficient in a good majority of cases and there
are plenty of dedicated graphics packages if more complex titling is
required for the timebeing.
