[MlMt] Copy text from subject

[Robert Anders]

Hi.

I know this might seem weird, but i very often do need to copy parts of 
the subject of an email to the clipboard. This is somehow _really_ hard 
to do because of the click-to-search-functionality and the behaviour of 
text selection in this part of the ui.

Can this be somehow improved? This would really make my day.


Thanks.

Robert.
