Search by regex special characters

[parauchf]

Added escaping to regex characters in the search term so that you can search by special characters like +, ( and [. Before this raised a regex exception.

I tested this code on my own app, but I don't thoroughly understand your code and I'm not a javascript pro. So I'd double check my work if I were you.

Thanks!

I was just looking into this problem, having tags like "C++" not showing any results. This works very well for me. Thank you!
