Some minor CS improvements to FormHelper

Replaced use of deprecated method getVar by get.
Improved DocBocks, mostly data types
Removed deprecated DocBock tag because it's an invalid use of such. This makes the method look like it was deprecated but in reality it's only one of the possible values of one of its parameters.
