no-url-protocols regex too aggressive (reports data-urls)

[benthemonkey]

Here's the offending code (in /lib/rules/no-url-protocols.js):

var isUrlRegex = /^(http(s?)):\/\/|\/\//;

It reports data-urls which have two consecutive slashes in them. The regex should be changed to report urls that begin with http(s):// or //. There are a number of ways to clean up the regex. Here's my suggested, simplified regex: /^(https?:)?\/\//
