Use std::vector instead of std::deque in QAlertDispatcher

As we never use {push,pop}_front std::vector works here perfectly.
Also reserve memory for std::vector out of lock.

speedup is under 0.2%.
Fix race condition in QAlertDispatcher

It was possible that QAlertDispatcher::dispatch() could access (lock)
mutex that was destroyed by main thread. Fix this by moving mutex into a
tag.
Change the program updater's URL for Windows and Mac OS X. Closes #1954.
