Merge lp:~trb143/openlp/splitter into lp:openlp

[Tim Bentley]

Add option to add a split to a song
This will split the verse when added to the service but keep the verse together for editing.
Useful for the 10 line hymn verses which need 2 slides to display.

Fix some iffy spelling

[Raoul Snyman (raoul-snyman)]

As per IRC, mrs_fly's suggestion was "Auto Split" and "Force Split". I'm going to e-mail the mailing list and see what others think.

[Tomas Groth (tomasgroth)]

The openlyrics export does handle the new spilt, which I believe it should. The import should of course also be able to restore it. I'll admit I'm not sure how it should be done...

review: Needs Fixing

[Raoul Snyman (raoul-snyman)]

Let's call the buttons "Overflow Split" and "Forced Split"

[Tomas Groth (tomasgroth)]

The openlyrics import/export still needs to handle the new spilt...
