put together git commit alias to act as interactive pre-commit

[masukomi]

git doesn't support interactive pre-commit hooks. the current version of the code hijacks the process to make that work, but then vim (or whatever editor) is screwed up when you try and edit the commit message (if not using -m "foo")

suggested solution:

1. remove the code that enables it to be used a pre-commit hook. it's not worth the consequences
   2.put together a tool / shell script / whatever that can be used as a replacement for git commit

tool should:

• check if changelog is present in commit files
• ask user if they want to add one
• call git commit creating one or skipping creation
