Revert "Remove deprecated form_for with strings or symbols"

This code was not deprecated. What was deprecated is the following:

  form_for(:foo, @foo)

Which now should be rewritten as:

  form_for(@foo, :as => :foo)

The following format is valid:

  form_for(:foo)

This reverts commit be797750e6ce866ea08307f63bf35304a965c8d4.
