Use simple forms where possible

[arteymix]

There's a couple of locations where it makes little sense to require JavaScript and simpler URL-encoded forms should be used:

• save user profile
• save genes in model organism page
• reset password & resend verification token

The search can be kept in JavaScript since it's dynamic.

This would have the benefit of enabling the use of Spring validation facilities to bind some error messages to the fields and provide a better user experience.
