The proposal to merge lp:~googol/openlp/central-settings-place into lp:openlp 
has been updated.

Description changed to:

Hello,

- fixed bug #1096559 (Central place for default settings)

I reworked the settings management. All core settings are now stored in the 
Settings class. The plugin settings are stored in the <my>plugin.py file. On 
start up the plugin settings are pulled in the central dict.

[Unfortunately I had to leave the default_value parameter in the value() method 
definiton, because we have some "dynamic" methods ("<myPlugin> %s").]

I also implemented a central dict to store old and replaced settings. This 
allows us to rename settings without losing the value saved. This allows even 
renaming a setting with uses ints (0/1) to e. g. a setting using bools 
(false/true).

Together with this rework I moved/splitted a few files.
Namely, I have moved the ScreenList class from openlp/core/ui to 
openlp/core/lib. When you look at trunk you'll see that in most cases the 
ScreenList was the only class imported from ui (indicating that it does not 
belong to ui). And basically the ScreenList is just like the ImageManager. It 
does not really display anything.
Furthermore, I splitted the ui.py file. Now we have a uistrings.py and ui.py 
file. While programming I noticed, that the UiStrings class does not require 
any module (other then the translate function).

In both cases (ScreenList and UiStrings) they caused import errors because 
importing them triggered other imports pointing to openlp.ui.Whatever; which 
then triggered the import of openlp.core.ui(.__init__) .

I hope that makes sense to you :)
