trying out to incorporate Facebook Like button in our forum thread.
by no means it is a finished feature, thus please feedback if there is any bug or room for improvement.

known issues are:
- instead of showing the forum content u like, it is currently showing only a generic description on ur profile page. but clicking on the like link works ok.
- add comment via the like button doesnt seems to function very well.

will remove this feature if it drastically slow down the webpages.
