Update Xdebug.py

Updated to increase the size of the click wait when clicking in the Xdebug Context, so a single click doesn't get picked up as two or more clicks.
I use this all day everyday and it works well but it is a mess.
But has a lot more functionality than the original sublimexdebug.
Note to self: Refactor to maybe use threads to avoid hangs on the little waits.
Note to self2: Consider sublimetext3 - python3 when refactoring.
