Fixed 'RemovedInDjango110Warning'

[foo-calls-bar]

Django==1.9.6, 1.9.7 complains about calling django.template.loader.get_template with a Context object, rather than a dict:

$ ./manage.py generate_favicon logo.png
Are you sure you want to continue? [Y/n]
Launch favicon generation and uploading
/home/foo/favicon/utils.py:67: RemovedInDjango110Warning: render() must be called with a dict, 
not a Context.
  output_content = template.render(Context({'tile_color': 'FFFFFF'}))

I simply updated the offending line in utils.py. It seems to work fine now with 1.9.6, 1.9.7, and runtests.py still succeeds:

$ ./manage.py generate_favicon logo.png
Are you sure you want to continue? [Y/n] 
Launch favicon generation and uploading

Coverage remained the same at 94.262% when pulling 79177ae on ryankaiser:merge into 6f95761 on ZuluPro:master.

Sorry about that last one. I accidently pushed another local branch to remote master, so I just re-forked and opened this new request. It should be good now.
