Pager: don't restrict new_desk to monitor boundaries

When FvwmPager is asked to place a window in its view via a
{new,configurenotify}event, FvwmPager was previously ignoring the
new_desk event if the window's monitor didn't match.

This isn't correct, and the monitor shouldn't be required for tracking a
new desk.

Fixes #433
