Lock notifications while executing dmenu

Browse Source 
When executing dmenu, the current notifications get "locked", by setting
their timeout temporarily to 0 and referencing them. So the notification
won't get closed (exept forcefully) and won't get freed while dmenu is
opened.

This is currently pointless, but as the dmenu call will become threaded,
it's necessary later.
