add seat sub command 'xcursor_theme'

Browse source 
New 'seat <name> xcursor_theme <theme> [<size>]' command that
configures the default xcursor theme.

The default seat's xcursor theme is also propagated to XWayland, and
exported through the XCURSOR_THEME and XCURSOR_SIZE environment
variables. This is done every time the default seat's configuration is
changed.
