Log file to keep tack of changes

[achkoe]

In order to keep track of access path, users groups
I would like to have some input field, e.g. besides the
"Create" button at page "Create access-path" or at page "Create group"
where I can put a comment why this group or access path has been created.
This comment should be written along with my user name (from login), a timestamp,
the action (e.g. created access path xyz) to a log file.
The same would be nice to have for the deletion of access path, groups, changes of access rights and so on.
These will support maintainance of SVN, e.g. cleaning up unused access paths or groups.
