Add support for phabricator styled output

Created by: MichaelAquilina

Add support for outputting results according to the table style defined in Phabricator's Remarkup Syntax. This allows a convenient mechanism of directly copying the output of csvlook to a Phabricator comment/story/wiki page.

For Example:

csvlook -P example.csv | xsel -i -b

Then just paste the results directly to see your table already formatted for you!
