v.2014w15

Changed the  way that highest score for the week was gathered.
Old way only looked at games played and ignored scores from teams on a bye.
New way parses the "Top Scores" sidebar instead.

Added scores property to league class

Updated parsers/gwjffl.py:
* Renamed parse_scores to parse_schedule because that's what it was doing
* Created new parse_scores to support new functionality described above

Renamed constants.scores_url_template to contants.schedule_url_template

Made minor template tweaks to pro.template and standings.template
