Added  'AwardsByBadge' view (displays the users awarded with a particular badge)

(details in the latest commit)
[also have I botched up this merge? Fairly sure I synched from upstream before I committed (certainly had the latest version in my desktop)]

some questions and concerns:

when passing an object into a context var (eg: a Badge instance as 'badge'), and no fields are accesed (eg: <h2>{{ badge }}</h2 ), is 'badge' automatically substituted with the output of '__unicode__'?

the 'AwardsByUser' view uses the template 'awards_by_user.html', which includes the 'awards_as_badges_list.html' template (which does not display the user involved in each award).
I've made a symmetrical 'AwardsByBade' view, which uses 'awards_by_badge.html', which includes 'awards_as_users_list.html'.
Have I correctly interpreted the naming convention?
Also, this 'included template' needs further insight into the user model, currently not defined
(I'VE ASSUMED THE USER HAS A 'name' AND A 'image.url').
Note, in modelling this new template around the one that WAS in '/unused', it lacks symmetry with 'AwardsByUser' (it shows details of the badge, where as 'AwardsByUser' does not show details of the user. Or at least, it WILL show details when 'includes/badge_full.html' is ready)

Where should the url of 'view awards of a given badge (AwardsByBadge)' work? I've assumed it should be 'badge/slug/awards' (to display awards of that badge), hoping this could conflict semantically with anything else.

I think there's a few discrepencies between the names of views in the wiki and in views.py

the current url for viewing awarded badges of a user is 'user/username/'. Shouldn't it be something explicit like 'user/username/awards'?

I'm also having concerns that the 'Award' bridge between Users and Badges may be confusing to users in terms of interpreting urls and the system (but who cares)
