Datetime with swapped year/timezone parsed incorrectly

While moving from Feedparser 5.1 to 5.1.3 the time detection changed in some 
ways.

With Feedparser 5.1 a string ``'Sun Jul 15 00:15:00 +0000 2012'`` was correctly 
recognized as

time.struct_time(tm_year=2012, tm_mon=7, tm_mday=15, tm_hour=0, tm_min=15, 
tm_sec=0, tm_wday=6, tm_yday=197, tm_isdst=0)

. After the updated it is recognized as

time.struct_time(tm_year=2000, tm_mon=7, tm_mday=15, tm_hour=0, tm_min=0, 
tm_sec=0, tm_wday=5, tm_yday=197, tm_isdst=0)

which is, obviously, not what we want.

To make this actually work with 5.1.3 I created my on parser using the dateutil 
library:

import dateutil
def dateutilDateHandler(aDateString):
    return dateutil.parser.parse(aDateString).utctimetuple()
feedparser.registerDateHandler(dateutilDateHandler)

Start by reproducing the reported date string through feedparser's date detection and compare its result with the expected time.struct_time from Feedparser 5.1. Review the registerDateHandler entry point and the dateutil.parser.parse workaround described in the issue. Done means the string yields year 2012, minute 15, and the expected weekday and day-of-year values.
