Instead of using a GET value in the URL, split on the path separators
and use the second element of the path as the key. This enables
putting the stream key in the appropriate settings in OBS, instead of
appending it to the stream URL manually.
This still needs a bunch of work, but this should be OK until the UI is
rewritten.
The command injects a <script> tag to open up a new window. Mod and
admin commands are only shown to mods and admins (no authentication
happens for this).
Resolves#8 for now.
