[patch] Add reverse counter variables to template "for loops"

Description

I had a need to iterate backwards through the counter (i.e. 24,23,22,21...1) while displaying the items in a list in the proper order. I propose the addition of forloop.counterr and forloop.counter0r variables to complement forloop.counter and forloop.counter0.

It's a simple patch and I've inlcluded it here:

                 'first': (i == 0),
                 'last': (i == len_values - 1),

I think it should be named "revcounter" and "revcounter0" or maybe "invcounter". Just one letter of difference between the two would be prone to mistakes.

(In [736]) Fixed #295 - added forloop.revcounter and forloop.revcounter0 variables to for loops. Also updated the docs and added unit tests to verify correct behavior. Thanks, Clint.
