vsync: choose vsync method automatically

Browse Source 
Choose the best vsync method for the user, instead of asking them to
frustratingly try every one of the options to see what works.

With this commit, the `vsync` option will take only a boolean value.

*--refresh-rate* 'REFRESH_RATE'::
Specify refresh rate of the screen. If not specified or 0, compton will try detecting this with X RandR extension.
*--vsync* 'VSYNC_METHOD'::
Set VSync method. VSync methods currently available:
+
--
* 'none': No VSync
* 'drm': VSync with 'DRM_IOCTL_WAIT_VBLANK'. May only work on some (DRI-based) drivers.
* 'opengl': Try to VSync with 'SGI_video_sync' OpenGL extension. Only work on some drivers.
* 'opengl-oml': Try to VSync with 'OML_sync_control' OpenGL extension. Only work on some drivers.
* 'opengl-swc': Try to VSync with 'MESA_swap_control' or 'SGI_swap_control' (in order of preference) OpenGL extension. Works only with GLX backend. Known to be most effective on many drivers. Does not guarantee to control paint timing.
* 'opengl-mswc': Deprecated, use 'opengl-swc' instead.
(Note some VSync methods may not be enabled at compile time.)
--
*--vsync*::
Enable VSync.
*--sw-opti*::
Limit compton to repaint at most once every 1 / 'refresh_rate' second to boost performance. This should not be used with *--vsync* drm/opengl/opengl-oml as they essentially does *--sw-opti*'s job already, unless you wish to specify a lower refresh rate than the actual value.
