Failure to parse URL that doesn't start with scheme but contains a query that contains a URL with a scheme

[mlhdeveloper]

Here's a simple example URL that fails to parse:

somedomain.com/?g=http://somedomain.com/

If you add a scheme to the front, it then parses properly:

http://somedomain.com/?g=http://somedomain.com/

I think the solution lies in changing this part so that it's only checking for :// near the beginning of the url and not anywhere in the entire url:

utbox/utbox/bin/ut_parse_lib.py

Line 15 in f8db838

preg_rfc1808 = re.compile("://")

utbox/utbox/bin/ut_parse_lib.py

Lines 257 to 258 in f8db838

	if not preg_rfc1808.search(url):
	url = "//%s" % url

I think this fixes it so that it's only checking for :// at the very beginning of the url or only after a scheme, i.e. only after any number of alphabetical or + characters (based on schemes handled by urllib.parse):

preg_rfc1808 = re.compile("^[a-z+]*://")
