Subject: ui-commit: add support for 'commit-filter' option

This new option specifies a filter which is executed on the commit
message, i.e. the commit message is written to the filters STDIN and
the filters STDOUT is included verbatim as the commit message.

This can be used to implement commit linking by creating a simple
shell script in e.g. /usr/bin/cgit-commit-filter.sh like this:

#/bin/sh
sed -re 's|\b([0-9a-fA-F]{6,40})\b|<a href="./?id=\1">\1</a>|g'

filter settings per repository.
