Provides the same benefits to scripts as exposing GIT_EDITOR, but
allows distinguishing the 'sequence' editor from the 'core' editor.

var: add GIT_SEQUENCE_EDITOR variable
In my case, I'm overriding the sequence editor in git rebase -i to do
some pre-processing on the todo file, but I'd still like to open up the
editor for further manipulation/verification of the todo steps. Just
using GIT_EDITOR here will clobber folks' expectations that their
custom-built sequence editor pops up (e.g. VSCode or Git Cola).
