(Jim note: Adds abstraction to the OAuth class to allow the ability to
perform OAuth via external browser, and adds an AuthListener to act as
the local auth server.)
(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.
Previously enabling and disabling bandwidth testing in a certain order
lead to the parameter being included in the stream key that is saved to
disk, making it impossible to disable the bandwidth test later on.
By doing this properly and using string concatenation instead of
modifying (appending to) the key_ value this will no longer happen.
The message boxes that tell you that the browser is initializing or that
you're authenticating with twitch are annoying on startup. It makes
sense to do it in the settings/autoconfig dialogs where you sort of need
to know what's going on while waiting for it to connect, but on startup
it's not really necessary and can be kind of annoying.
