Switch to versioneer-provided versions everywhere

WSGI-compliant server someday, and also silences some startup warnings
about missing application configs.

+* Brian Warner
+* License: Public Domain
+* Version: 0.7+
+
+This file helps distutils-based projects manage their version number by just
+creating version-control tags.
+
+For developers who work from a VCS-generated tree (e.g. 'git clone' etc),
+each 'setup.py version', 'setup.py build', 'setup.py sdist' will compute a
+version number by asking your version-control tool about the current
+checkout. The version number will be written into a generated _version.py
+file of your choosing, where it can be included by your __init__.py
+
+For users who work from a VCS-generated tarball (e.g. 'git archive'), it will
+compute a version number by looking at the name of the directory created when
+te tarball is unpacked. This conventionally includes both the name of the
+project and a version number.
+
+For users who work from a tarball built by 'setup.py sdist', it will get a
+version number from a previously-generated _version.py file.
+
+As a result, loading code directly from the source tree will not result in a
+real version. If you want real versions from VCS trees (where you frequently
+update from the upstream repository, or do new development), you will need to
+do a 'setup.py version' after each update, and load code from the build/
+directory.
+
+You need to provide this code with a few configuration values:
+
+ versionfile_source:
+    A project-relative pathname into which the generated version strings
+    should be written. This is usually a _version.py next to your project's
+    main __init__.py file. If your project uses src/myproject/__init__.py,
+    this should be 'src/myproject/_version.py'. This file should be checked
+    in to your VCS as usual: the copy created below by 'setup.py
+    update_files' will include code that parses expanded VCS keywords in
+    generated tarballs. The 'build' and 'sdist' commands will replace it with
+    a copy that has just the calculated version string.
+
+ versionfile_build:
+    Like versionfile_source, but relative to the build directory instead of
+    the source directory. These will differ when your setup.py uses
+    'package_dir='. If you have package_dir={'myproject': 'src/myproject'},
+    then you will probably have versionfile_build='myproject/_version.py' and
+    versionfile_source='src/myproject/_version.py'.
+
+ tag_prefix: a string, like 'PROJECTNAME-', which appears at the start of all
+             VCS tags. If your tags look like 'myproject-1.2.0', then you
+             should use tag_prefix='myproject-'. If you use unprefixed tags
+             like '1.2.0', this should be an empty string.
+
+ parentdir_prefix: a string, frequently the same as tag_prefix, which
+                   appears at the start of all unpacked tarball filenames. If
+                   your tarball unpacks into 'myproject-1.2.0', this should
+                   be 'myproject-'.
+
+To use it:
+
+ 1: include this file in the top level of your project
+ 2: make the following changes to the top of your setup.py:
+     import versioneer
+     versioneer.versionfile_source = 'src/myproject/_version.py'
+     versioneer.versionfile_build = 'myproject/_version.py'
+     versioneer.tag_prefix = '' # tags are like 1.2.0
+     versioneer.parentdir_prefix = 'myproject-' # dirname like 'myproject-1.2.0'
+ 3: add the following arguments to the setup() call in your setup.py:
+     version=versioneer.get_version(),
+     cmdclass=versioneer.get_cmdclass(),
+ 4: run 'setup.py update_files', which will create _version.py, and will
+    append the following to your __init__.py:
+     from _version import __version__
+ 5: modify your MANIFEST.in to include versioneer.py
+ 6: add both versioneer.py and the generated _version.py to your VCS
