Fix Bug: blog title won't submit with weird characters

[Tguntenaar]

As Joe pointed out submitting a blog with these characters: [ ] in the title does not work since they are not valid characters in the keys of the social contract. I made a small change to only allow numbers, capital and lowercase letters. Everything else is replace in the title by an empty string. That is done by this regex: /[^a-z0-9A-Z]/g
