Fix minor issues with Form Submit from Role Overlay (DRYed) [2/4]

In fixing a checkbox form submit issue, I figured out an easy way to DRY the form code
that is implemented in this pull.

I also fixed the checkbox issue (changed to a select box)

Since I was playing w/ select boxes, I also corrected the network barclamp to use
select for deployments instead of the cheesy textbox.
