v0.5.0

This is a major one, containing two larger features, that require some changes in the configuration format. This release is fully backwards compatible to v0.4.1, however deprecates two uses that will be removed in a future version.

• New feature: Part specific configuration
• New feature: File specific configuration
• New feature: parse option can now span multiple line (allows to comment complex regular expressions. See - re.VERBOSE in the Python documentation for details, this testcase as an example.)
• New feature: --allow-dirty (#42).
• Fix: Save the files in binary mode to avoid mutating newlines (thanks @jaraco #45).
• License: bumpversion is now licensed under the MIT License (#47)
• Deprecate multiple files on the command line (use a configuration file instead, or invoke bumpversion multiple times)
• Deprecate 'files =' configuration (use file specific configuration instead)

v0.3.2

• bugfix: Read only tags from git describe that look like versions
