bug#15619: M-x list-packages should also show link to homepage / source

[Swaroop C H]

Hello,

I hope this is the right forum for this question, please direct me if otherwise.

When I run ~M-x list-packages~, and click on a package name, the description is 
usually vague on what it means, and it would be great if there was a link to 
the source / github link (just like the website http://melpa.milkbox.net/ 
displays the Source column)  so that I can understand what it actually does.

For example, ~pony-mode~ says "Minor mode for working with Django projects 
[github]" and that ~[github]~ doesn't actually link to anything and that 
description is not helpful to what it actually does.

Further examples (as pointed out by jlf on freenode.net#emacs IRC) are 
"lisp-editing" which says "lisp editing tools" in the description and 
"fuzzy-match" which says "fuzzy matching [wiki]" in the description.

This is definitely not nitpicking about those packages, but a request that 
there be a standard homepage / source (github, etc.) link in the description 
for each package, similar to how HomeBrew package manager on OS X works.

Thank you!

Regards,
Swaroop
