Title: Simple cleanups...

... which I didn't want to get mixed up with the more serious changes to follow in the next pull request. In this one we have just:

1. Don't exit on pressing "Back" in filemanager
2. Make info messages about highlight short enough to be displayable.
3. Change "Updating HighLight data..." to Debug() as it is non-blocking and irrelevant to the user (especially because it is displayed on files which have no highlight data anyway and this may cause confusion).
4. Don't crash when user presses ENTER or FW select buttons on empty history, just display an appropriate (short) message.
