Multiple checkbox submissions from admin UI

[haygoodg]

While adding a Checkbox field to a contact form, if there is text in the last option input field when you hit Save, SS adds all the checkbox options, not just the new one. So hitting Save multiple times (which the user would do, thinking s/he's saving the form), it continually adds them all over again.

The problem goes away by hitting the + button next to the last option, to save and show an empty field, then hitting the main Save button.

While they may be expected functional behavior, it is not as intuitive as it could be for the user's sake.

Tested on SS 2.2.0 on XAMPP for Windows Version 1.6.4 (Windows XP, MySQL 5.0.45, PHP 5.2.4)
