fix(wm): restart cmd processing thread on fail

This commit makes some changes to process_command and process_event to
bring them more in line with newer modules, while primarily making sure
that the thread spawned in process_command will be restarted if
necessary.

In the future I might pull out the process_command and process_event fns
from the WindowManager struct and have them take an
Arc<Mutex<WindowManager>> instead which acquires the lock on every call
like the reconciliators and border_manager do.
