Apostrophe in e-mail address causes sql failures on New Thread (at least).

The apostropie is not being escaped properly in the SQL creation. This is possibly also evidence of an SQL injection vulnerability, however I have not persued this far enough to check yet.

An apostrophie is allowed in an e-mail address (e.g. Mike.O'Hara(at)test(dot)com) according to the relevant RFC's so it should be accepted.

Note that the e-mail address parsing code also fails to recognise the e-mail address above as valid and therefore creates an incorrectly formed <A> tag for the address.
