add the word "fix" to the post-commit hook command list

[xris]

I've found myself committing messages like "fix #333", so I thought it would be a nice addition to have the post-commit hook grab that (currently, it only grabs "fixes"). Might want to also consider "fixed", too.

full list of commands from my personal copy:

    _supported_cmds = {'close':      '_cmdClose',
                       'closed':     '_cmdClose',
                       'closes':     '_cmdClose',
                       'fix':        '_cmdClose',
                       'fixed':      '_cmdClose',
                       'fixes':      '_cmdClose',
                       'addresses':  '_cmdRefs',
                       're':         '_cmdRefs',
                       'references': '_cmdRefs',
                       'refs':       '_cmdRefs'}

after some user requests, this list has been updated to add "see" as well…

    _supported_cmds = {'close':      '_cmdClose',
                       'closed':     '_cmdClose',
                       'closes':     '_cmdClose',
                       'fix':        '_cmdClose',
                       'fixed':      '_cmdClose',
                       'fixes':      '_cmdClose',
                       'addresses':  '_cmdRefs',
                       're':         '_cmdRefs',
                       'references': '_cmdRefs',
                       'refs':       '_cmdRefs',
                       'see':        '_cmdRefs'}
