Autofilled custom fields in Firefox
Firefox autofills/autocompletes custom fields for users even although they should be empty.
I created a new text custom field for users without default value. Then, in the user configuration the custom field was autofilled with the login name. Obviously this is wrong. Other browsers (IE, Opera, Safari) haven't this fault.
Tested on Redmine 2.1 + 2.2
This seems to be related to #240.
