patch changes are now in patch name and mentioned in changelog entry

- bump to 5.4.1
Changes between 5.4.1 and 3.6
* Python #7776: (ssl_support) Correct usage of host for validation when
tunneling for HTTPS.
* Issue #154: pkg_resources will now cache the zip manifests rather than
re-processing the same file from disk multiple times, but only if the
environment variable PKG_RESOURCES_CACHE_ZIP_MANIFESTS is set. Clients
that package many modules in the same zip file will see some improvement
in startup time by enabling this feature. This feature is not enabled by
default because it causes a substantial increase in memory usage.
* Issue #185: Make svn tagging work on the new style SVN metadata. Thanks
cazabon!
* Prune revision control directories (e.g .svn) from base path as well as
sub-directories.
* Added a Developer Guide to the official documentation.
* Some code refactoring and cleanup was done with no intended behavioral
changes.
* During install_egg_info, the generated lines for namespace package .pth
files are now processed even during a dry run.
* Issue #202: Implemented more robust cache invalidation for the
ZipImporter, building on the work in Issue #168. Special thanks to Jurko
Gospodnetic and PJE.
* Issue #220: Restored script templates.
* Renamed script templates to end with .tmpl now that they no longer need to
be processed by 2to3. Fixes spurious syntax errors during build/install.
* Issue #218: Re-release of 3.8.1 to signal that it supersedes 4.x.
* Incidentally, script templates were updated not to include the
triple-quote escaping.
* Issue #213: Use legacy StringIO behavior for compatibility under pbr.
* Issue #218: Setuptools 3.8.1 superseded 4.0.1, and 4.x was removed from
