Tickets Check if JavaScript is enabled

[Alpha1]

This is a simple request. For specific categories its useful to see if a user has JS enabled because:

1. Users without JavaScript are likely to get blocked from registration by antispam protocols
2. Users without JavaScript may get stuck on registration timers (Advanced Forum Rules)
3. It is useful for resolving technical issues encountered by users

So please add a function that will display if the user has JS enabled.
