Limit the amount of hashtags people can put in their Gallery uploads.

I probably use a lot of hashtags, but mine are all relevant to the build, like #3beds or #2story. I've noticed #cityliving is used a lot even for houses that don't seem suited for the city and it seems like lately, almost every thing I run across on the gallery uses the hashtag #sexy (which I really don't understand).... I don't know if I'd like to be limited to the number of hashtags I could use, but I've gotten used to not using a lot of words since I started using Twitter, so I'd give it a go. :p
