v0.2.0

Changes:

• Properly strip lines that occur after the "snip" line in a commit message. This is usually the line that tells git to ignore the diff in a commit message if you use git commit -v.
• Violations are sorted by position, so that violations that occur earlier in the message appear at the top of the output.
• This and future releases will only provide 64-bit downloads. 32-bit can still be built from source.
• Documentation updates and code cleanup.
