Remove SHA stability note from readme
Turns out, it isn't true though the diffs are still empty, i.e.
$ git log --name-status --no-merges b1..b2
produces bogus output when b1 is the a branch from the main hg repo and
b2 a fork of it. But
$ git diff b1..b2
still produces the correct result.

hg2git.py: Disable parsing Signef-off-by lines and add -s to enable
IMHO it's highly unusual to have these lines in hg projects but who
knows. As it's slow to parse these types of lines (with regex), it's
disabled by default and the 'author' command of git-fast-import isn't
used at all.
It can be enabled by giving the -s switch to hg2git.sh.

Only attempt to verify heads hg has, too
In the git repo there may be any number branches that are not hg
imported branches, so it doesn't make sense to print warnings when a
non-hg head isn't at what it was last time.
Now we get a list of branchtags hg has and only verify these.

hg2git.py: Add support for extracting authorship from Signed-off-by lines
Unfortunately, it's not configurable yet (read: cannot be disabled) as
it may take some time to match against regex all the time (especially
from some initial import).

Speedup: Use manifest and compare checksums to detect changes
Instead of feeding in everything or only something and getting merges
wrong, build up a list of changed (incl. added) and deleted files by
1) comparing manifest (deleted, added)
2) comparing checksums if file is present in parent and child (change)
The hg-crew and mutt imports now go in <15 minutes and md5 sums match.
Thanks to Theodore Tso for the hint.
While at it, fix a regression that upon incremental import start we
always merged a branch plus initializing it. A single test showed that
the new detection get starting off from a merge commit right, too.
