Typos and Special Thanks added
Added some YouTube stuff

Changed shortened youtu.be links to work better with webOS2.2.4 version
of YouTube app and added ability to load YouTube vids in webOS2.1.2
version of app if installed.  Also added a HOWTO and patch file to make
this easier.
Typo fix
Location pref for TrendingTopics

Also, fixed a refresh bug for trends.
Removed continents from trends

...apart from Australia.  Twitter doesn't seem to trend continents, only
countries and smaller. Weird.
