[15.15] Clicking mod portal login Cancel button acts like OK

[rmrector@gmail.com]

When logging into the mod portal, clicking the "Cancel" button does the same thing the "OK" button does: it warns if the username is empty, and tries to login otherwise.
I expected it to go back to the main "Mods" window.
The Esc key and tabbing twice from the password prompt then pressing Enter do work as I expected.

Thanks for the report. It's now fixed for the next version of 0.15.
