Date fix

Sometimes the MTG Top 8 pages have different information on the "Format and Date" line [like this event](http://www.mtgtop8.com/event?e=7959&f=LE) that includes number of players or other information.  
This caused the "Date" to be parsed as "259" instead of "3/08/14".  

This fix pulls the valid Date (in all formats that I found it in) correctly.
