git-webrev: add flags --base and --head

[edvbld]

Hi all,

please review this patch that adds two new flags to git-webrev - --base and --head. The flag --base behaves like -r, --rev, that is determines the base commit to compare against. The flag --head determines the commit to use a HEAD for the comparison, that is the most recent commit for the comparison. The two flags --base and --head allows a user to create a webrev between two arbitrary commits (without forcing to check out the head commit first).

Testing:

• Manual testing on Linux x64

Thanks,
Erik
