Resume: Let user set gender to "unspecified"

[Aaron Wells]

Currently the "Personal Information" section of the resume lists "male" and "female". This is an optional field, inasmuch as it starts out unselected. But, once you select one, you can't go back to being unspecified.

I suggest:

1. Adding a third option, "(Unspecified)" which will cause the user's gender to not be displayed on their resume.

2. Adding a fourth "other" option, with a blank text field, to accommodate people who identify outside of the male/female binary.

As a first step, here's a patch to allow a user to set their gender back to "not specified": https://reviews.mahara.org/2296
