Merge lp://qastaging/~suutari-olli/openlp/combined-bible-quick-search into lp://qastaging/openlp

In this merge:

Refactored the code for combined search.
- Added: def on_quick_reference_search(self): and moved definition of reference search there.
- Added: def on_quick_text_search(self): and moved definition of text search there.
- Removed some un-needed code duplicates (Double finalizing, 3rd normalizing of mouse cursor)
- Searching scripture ref with shorter than 3 char search is now possible (G1 = Genesis 1)

Also removed “Search” from “Search Text or Reference…” since it does not fit the box properly.

Noticed one line was longer than 120, splitted it.

- Noticed I had left an old comment to a wrong place. (Moved it to def on_quick_reference_search)

In this merge:
Splitted scripture reference error into small pieces, built error from them.
This still needs to be moved away from uistrings.py

Noticed "No bibles available" was defined 3 times > Moved it to uistrings.
Added "Must have bibles" condition for other error messages in combined search.

To do:

Add a setting for controlling visibility of the no results error, it may be of annoyance.
Tests...

Added "Search Settings" > "Don't show error fofr no results in combined quick search" checkbox
for controlling whetever no results message is shown or not.

- Fixed layout for the new setting, cleanup for biblestab.py from process.

Merge to trunk on 9.4.16

Noticed the identification for scripture reference error got messed at some point, fixed it.
