Add a tab for Qt debug features. Initially provides access to dumpObjectTree() on
Application and MainWindow objects. This dumps the object's child objects to the
log.
Add Accept, Apply, Reject methods to settings pages to mirror dialog. This will
allow settings pages to handle these events at a more granular level and will
allow common behavor in the base class.
The rowsAboutToBeRemoved signal from the model provides a parent index, but with
QStandardItemModel, top level items are added to an invisible root item that
doesn't have a valid index. This causes the range check to miss top level items
due to a perceived parent mismatch. When the load completes, it attempts to
access an object that has been deleted.
- Group list and settings so they can be enabled/disabled together.
- Make default selection shortcut list. Previous behavior set options
for the first item, but didn't highlight selection.
- Rename ItemClicked to CurrentItemChanged to reflect correct signal.
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).

Previously, the number of processes spawned was always
QThread::idealThreadCount() (returning the number of logical CPU
cores). On new systems with many cores, however, this can result
in 12, 16, 24, or ... processes being spawned, which is a bit
excessive.
This establishes a new config variable,
'max_numprocs_tagclients' within the Settings group, in order
to limit the maximum number of tag client processes that get
spawned. It also adds a means of setting this via the Behavior
page in Settings. It can be set to any integer in the interval
[1, QThread::idealThreadCount()]; it defaults to the maximal value
so as to emulate the old behavior.
QTimeLine duration must be greater than 0. If set to 0, a default of 1000ms will
be used. To avoid this, enforce a minimum of 1ms for pause and cross fade values
if those fades are enabled.
