Instead of immediately saving, which leads to poor performance,
and possible hardware damage (see #6057), limit saves to once
per second (similar to how KDE does it). It also guarantees
that only one save is required per second, by sharing a QSettings
object, and establishes a signaling framework to put other
setting save events into (but only uses this for the two major
offenders: playlist tab switching and window resizing).
This is in contrast to 6a312e7, which simply deferred the save
until program exit, and caused problems for some people (see #6217
and #6209).

* Replace Nokia sidebar widget with QTabWidget
The old sidebar widget was written by Nokia 10 years ago
and was a hand made hardcoded mess of widgets trying to
emulate a QTabWidget.
This commit completely replaces it with a widget of the
same name (FancyTabWidget) but is a much simpler subclass
of the standard QTabWidget allowing for a 50% code reduction.
There is still some manual draw code copied over to get the
exact same look of the previous widget but this is not strictly
necessary and can be later refactored with simpler drawControl
code based on styling preferences.
Benefits:
- 50% code reduction
- Easier to understand standard QTabWidget mechanics
- Built-in support for re-arranging and closing tabs
* Save and restore sidebar tab order
Allow the user to rearrange the tab order by dragging
tabs to a new location. Tab order is saved on exit and restored
on start
* Fix some code formatting issues
