This removes the gender selection field from the registration page on newer 1.4 forums.
If upgrading from 1.1.1, you need only to install the newer XML file.
No need to upgrade if this add-on is already working for you. This is a minor fix to make sure that all file name casings are consistent.
Added custom gender to message/conversation view
Removed gender search criteria from admin user search page
Changed user criteria for promotions/etc. to use a text field instead of a drop down gender select field (which is also still likely to break things)
