Meta: WP Forums account signup — work fields should be checkboxes

[Vynce]

when attempting to sign up for a Forums account, the “I use WP at work” and “I make my living…” and “I’m a consultant” fields are initially presented as text boxes. Later, they are checkboxes, and there are bugs relating to turning them off.

(Specifically, they were showing up on my profile despite not being “checked”. In order to make them go away, i had to check them, save, uncheck them, save again.)
