[NEW] preview csv as a table in output window

Preview CSV (as a html table) in a new Window.
Uses system ruby (1.8.7 on my machine) to parse the CSV. Unfortunately this version of ruby has issues parsing tab separated files, therefore this command only works with "text.tabular.csv"

Have tested on TextMate 2.0-alpha.9479 (I no longer have TextMate 1 installed on my machine)
