[PATCH 1/3] gitweb.cgi: git_blame2: an alternative simple working git blame

This patch adds an alternative simple working git-blame
called git_blame2().  Simple, because it displays just
three columns: the commit, the line number and the line
of code.  Alternative, because the original git_blame()
is left untouched.  Lines of code are printed html
escaped, but as-is.

git_blame2() uses git-blame as opposed to git-annotate
used by git_blame().
