Added initial version of SU API implementation for freshers fayre, still needs error checking adding, though now ready for testing, improvements welcome.

Allow admins to remove unrequested junk items, no questions asked. (plus a little extra error handling)

More work really needs doing to ensure titles going into the database are encoded correctly.

Adds a agree to TnC's tick box to the signup page... and wont let you submit untill you do.. also fixes the not enabling the submit button when you've filled out the last field problem

Needs checking for agreement in the php too.. otherwise non JS enabled people will still get away with it

UI and validation for the new signup system, actual backend functionality is started but mostly missing

Makes password check function in session class public

Allow members to specify a blog feed in the options component, and generate planet configuration files dynamically. Fixes #64
