Print log of new commits when updating an existing branch from version control

Description
I thought it would be nice to be able to run 'jhbuild update' and be given a list of the new commits. Turns out, it is is quite nice ;)
Not so useful for 'build' because the output scrolls off the screen so quickly. With the current patch logs are printed during 'build' as well, but it's not important to me either way.
To make this a more robust system, we could write into a separate log file as well for later user perusal (git doesn't actually provide a simple "what is new" command, although there might be easy way to implement one) but that's going beyond my use case anyway.
Currently only implemented for git
