Edited QGmailNotifier.cpp
because it would not use google-crhome to open/view/compose mail.
Kept using Firefox instead if it was installed, despite the fact
that xdg-open would use the default (which is set to google-chrome 
on my box.)

I looked over the code in the QT lib and cold not understand why 
it would not work. the code used xdg-open before trying individual 
browsers. So I hacked the qgmailnotifier code :-)

It sets the program to open stuff with /usr/local/bin/runBrowser

ALSO put in a restart function because sometimes it hung up,
with the icon continually flashing as if it was connecting.

Diffs are included.
