Add manifest hash to commit messages for easy signing

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Here's an example:

This is the current manifest hash:

 e06d11165178d03c296ea7e7854f91e612a8d6bf

It was copied from the HG: comment lines that are added to the commit.
Then I wrote this commit message, signed it, then closed the commit.

The manifest hash is a hash of all the files in the project together
with the hashes of manifest's parents. Thus, signing the manifest hash
allows us to verify the entire state of project at the time of the
commit.
