Allow new-lines in Method descriptions

[dmalouf]

The descriptions of Methods (ex. POST, GET, etc.) can have new-lines on data-entry, but the new-lines are ignored in this Documentaiton module.

As it stands right now, new-lines are, effectively, just spaces. This can make the description of a given method more more difficult to read when there is more than a few sentences.

See the screen-shot for an example of the desired effect: I have included the CSS ( white-space: pre ) on the related element.
