Added video meta description to video search result objects with hashtag fix

[RedNinjaX]

Noticed that while the API doesn't return the true video description it does return its meta description, so I've included that in the video search results. Also this was forked from @ChunkyProgrammer's hashtag fix branch, so that's included too.

Also "isLive" was returning the wrong value so fixed that too.
