[BUG] Marker View Lk column does not show status of locked markers

[LarsF 52]

Just noticed this when using locked markers in time.

You get the status on the tool panel selecting it - but there is a column to show Lk status which is always blank.

So when mixing locked and non-locked markers - it is hard to differentiate and have to do trial and error on each marker.

Really smart use of markers to be able to lock certain to video scenes and those that used for musical purposes following tempo.

So quickly seeing the locked markers is really useful.

Thanks.
