Attempt to fix semicolon problem with registration emails

[mouser]

SMF uses a ; separator instead of the common & when sending out emails with login validation links and password reminders.
As a result, it seems that some email clients parse these links wrong.

I've tried to change the code now to use & instead of ; so please let me know if you spot any troubles with your validation or password reset emails (you can email mouser@donationcoder.com).

Might be an idea to place a small banner about this on the main homepage (not forum home, the sites homepage) so users who try to register can see it without having to hunt through forum categories.

Something small perhaps (Like an image containing the text "Registration Problems? - Click Here") with a link to this might be ideal?
