Brian Ashworth ff7d979d99 cmd_xwayland: add force for immediate launch
This just adds a force option to cmd_xwayland that allows for xwayland
to be immediately launched instead of lazily launched. This is useful
for slower machines so it can be part of the startup time instead of
when the user is actively trying to use it
