Title: Tunnelblick 3.4.2 (and other changes)

Tunnelblick 3.4.2 was released today. I've made changes to the cask file that:
* update to the latest version;
* specify the supported Mac OS X versions;
* specify the GPL; and
* add an uninstall stanza to remove a launchctl item and quit the app if running.

I don't really like the verbose version number. I was tempted to change it to SemVer.org style
("3.4.2+4055.4161") or just omit the build specifier completely.
