Merge lp:~3v1n0/unity-control-center/grouped-compiz-gsettings-support-x into lp:unity-control-center/16.04

[Marco Trevisan (Treviño)]

Appearance: create GroupedGSettings class to manage group of gsettings sharing the schema

Settings might have the same schema, but different path. With this class we manage them
all at once. In this case we use this to correctly read the setting values depending on
the compiz profile we're actually using.

looks fine but is there is a need to SRU those changes to xenial?

> looks fine but is there is a need to SRU those changes to xenial?

This is part of the work needed to get proper lowgfx setup working, and to fix issues with settings not being properly preserved between the two modes.

Now, being Xenial the main target for unity7 at this point, I think it just make sense to put the fixes we have there.
As they're proved to run fine in the current dev releases for a while.

appearance: fix a typo causing not using the proper variable on vsize

Not triggering a bug for how the code is made, though.

GroupedGSettings: ensure we ref the variant's before setting them

Otherwise when we set floating references they get consumed
by the first call to g_settings_set_value and the value becomes
invalid. Thus we need to remove the floating reference, and
manually ref and unref.
