Please add (upstream) changelog to vcsh

[Thomas Koch]

Hi,

I've just updated vcsh in Wheezy and was curious to see what changed, but 
neither in the Debian package nor in the upstream Git repository is a project 
changelog.
Could you please be so kind to add one? It'd be a shame not to have one, since 
there are so nice ways to autogenerate changelogs from Git commit messages.[1]

[1] I know of git-dch, but there must also be Debian independent tools.

Best regards,
