[PATCH 3/3] gitweb: Remove git_blame (superseded by git_blame2)

[Petr Baudis <pasky@suse.cz>]

This patch definitely removes git_blame() from the source and renames
git_blame2() to git_blame(); it was already the default handler for the
blame action for a long time and it has been actually broken for some time
now (I'm not sure how long), so noone probably cares about it much (I have
an alternative trivial patch to fix it too). All the information listing is
already included in git_blame2() output now.
