Added favicon for admin

[niels_bom]

Added a favicon in .png format for the admin. I used the colorscheme of admin.

Just tried it out, works nicely with FF 4.0.1 and Safari (both on Mac).
The design of the icon could be a little bit more near the favicon of djangoproject.com, at least the rounded corners

[Harro]

Could you add a block around it? So it could be changed without too much hassle

[DHessing]

I agree on the rounded corners and the block.
Works on FF 3.6.17 on Ubuntu

I will also do the following check (thanks for the idea to Klaas van Schelven):

www.example.com has favicon A
www.example.com/admin has favicon B
Then check that www.example.com won't ever show favicon B.

Will check this in IE7+, FF3+, Chrome, Safari

Do we want a Django favicon for the admin? I would have thought the admin should get the same favicon as the rest of the site. It is, after all, just one contrib app. No other contrib app or 3rd party Django app would get Django branding.

[Stephen Burrows]

I agree with lukeplant - this seems odd and unnecessary.

[Harro]

True, but most apps don't provide templates and css either. The admin does so why not add a favicon

[Luke Plant]

I've thought about this more, and I don't think its appropriate.

Unlike CSS and styling, favicons are all about site identity. Adding a favicon for the admin would be asserting brand identity of one of the tools used to make the website, or one section of the website, which doesn't seem appropriate for any web development tool. I wouldn't expect a component provided by any other web framework to do this. I don't even like it when an out-of-the-box solution like WordPress provides its own favicon (I don't know if they do any more). When you see those default favicons on websites, they look unprofessional - I only expect to see the WordPress favicon if I'm on wordpress.com.

I don't know what other core devs think, none has contributed so far. I'm going to close as wontfix, but please bring it up on django-devs if you'd like other opinions.
