Works around a bug in Qt where setWindowTitle called on a native window
that hasn't been initialised yet causes the title data to be lost,
resulting in the window's title never being set.
Use the QAction provided by QDockWidget with new Qt connection rather
than creating a new one for each dock.
Separate extra browser docks from extra docks, the latter is meant for
plugin/integration docks.
(Jim note: This gives the ability for auth login callbacks to know which
specific service type is being used. For example, with something like
YouTube, there's multiple variants: RTMP, RTMPS, and HLS. This way, the
service login callback can determine how it wants to treat the login
procedure depending on the specific type of service.)
Code submissions have continually suffered from formatting
inconsistencies that constantly have to be addressed. Using
clang-format simplifies this by making code formatting more consistent,
and allows automation of the code formatting so that maintainers can
focus more on the code itself instead of code formatting.
