Flesh out 'depends' command to display dependencies' status, and halt if

all requirements aren't met.  (Also, check planned install location for
the dependencies, as well as checking sys.path.)  Also:

* Allow 'Feature()' objects to include 'Require()' objects, so that
  dependencies can be optional

* 'Require()' objects can set a homepage, whose URL will be displayed by
  the 'depends' command if the dependency needs to be installed.

* Misc. fixes/refactoring of version validation to properly handle
  "unknown" versions, and to decouple version fetching from version
  checking.

* Updated TODO to remove various completed items.
