Just suppress the spurious IndexError when it happens. Rely on the environments where the behavior doesn't fail until the upstream issue can be resolved. Fixes #201.

Merge pkg_resources.Environment.__getitem__() code cleanup (pull request #47 and subsequent changes).

Correct sort order by using list.sort with support for 'key' and 'reverse'. This method is less efficient, but allows the tests to pass.

Restore install._install with a comment to capture its requirement on earlier NumPy versions. Fixes #199.

Since paths are case-insensitive on Windows, zipped egg modules may be loaded
using different but equivalent paths. Importing each such different path causes
a new zipimporter to be instantiated. Removing cached zipimporter instances must
then not forget about removing those created for differently spelled paths to
the same replaced egg.

Other missed zipimporter instances are those used to access zipped eggs stored
inside zipped eggs. When clearing zipimporter instances got a given path, we
need to clear all the instances related to any of its subpaths as well.
