[PATCH/RFC 1/2] Add sequence.format to interactive rebase

[William Clifford <mr.william.clifford@gmail.com>]

Allow user to customize the format of commit table in interactive
rebase todo file. Short hashes are still required to be the second
column so these are added to the format if not already present.
Defaults to oneline as before.
