Allow a max number of newlines to be passed to {% condense %}.
Review Request #4735 — Created Oct. 13, 2013 and submitted
Allow a max number of newlines to be passed to {% condense %}.
The {% condense %} template tag is no longer hard-coded to 3 newlines.
It can be passed the number of newlines it should condense down to.
Unit tests pass.
Tested with some changes I'm making to an e-mail template.
