Update Ubuntu PPA install instructions

This adds a check to change the capture settings to use 2 channels when
a channel number is encountered that would otherwise be interpreted as
SPEAKERS_UNKNOWN.

Although these values aren't used in capture mode, set these to the
default values just to be safe.

This changes the the requested buffer length to 25ms.

Because other capture methods may end up needing to share this code,
separate the window finding source code to window-helpers.c and
window-helpers.h.

This include a function to fill out a property list with windows, a
function to find a window based upon priority/title/class/exe, and a
function to decode the window title/class/exe strings from a window
setting string.

Add udev support to v4l2 plugin.

Fix cmake policy warning

This adds code to set up the udev monitoring library and use the events
to detect connects/disconnects of devices.
When the currently used device is disconnected the plugin will stop
recording and clean up, so that the device node is freed up.
On reconnection of the device the plugin will use the event to
automatically start the capture again.

This adds a small helper library to the v4l2 plugin that uses udev to
get events for v4l2 devices.

This adds a cmake module to find udev/libudev for linux.

Add monitor selection and properties to Monitor Capture (Win)

Function enum_monitors would always stop after first found monitor due to wrong return value.

This should fix blending issues on stream/recording that weren't visible
in the preview

Instead of limiting this to an apple-specific define, just limit it to
OpenGL -- because this particular effect file cannot be used with
Direct3D.

The graphics subsystem was not being freed here, for example if a
required effect failed to compile it would still successfully have the
graphics subsystem sans required effect.  The graphics subsystem should
be completely shut down if required libobs effects fail to compile.

This should probably be revisited if the preview can be rotated in 3D,
or someone comes up with a good 3D manipulation idea for the preview

If you have an item with width = 0 and height = 0 close to (0, 0)
clicking anywhere in the preview window would select them

The remuxer thread was only started if there was an actual remux job,
which resulted in the remuxer thread not being able to call the worker's
destructor (because it wasn't running)

test is a reserved name.

This was sorely needed for debugging stream issues.

Add option to use Sparkle for updates
