Suggestion: adding submitter details to log

[Harri Salokorpi]

Hello,

It might be useful to separate committer and patch author (or submitter) in 
log. This way patch integrators could keep track of the submitted patches and 
contact correct people when things break/change.

For merges, the submitter could be pulled from merged-from repository. For 
emailed patches either sender address or email-address in patch headers could 
be used.

Adding the field to revision file looks quite simple, and pulling the 
submitter details from email/merge is certainly doable.
