Gitweb upgrade on camel

We've been running the same ancient version of gitweb (a 2009 vintage)
ever since moving to git. It had a few customizations, which made
upgrading non-obvious.

I've now done so though, and made some significant changes to our
customizations. It's live on http://git.perl.space, which is a separate
vhost but runs on camel on top of the normal perl.git.

Please have a look at this version and report any issues.

The changes:
- Now using stock gitweb, automatically upgraded with git
- Tweaks to the blame view were dropped at least temporarily
- Custom search for and custom snapshot generator moved to
  gitweb.conf so they still work
- blame/history/snapshot views should no longer be indexed by bots,
  we'll see how well they respect rel=nofollow and robots.txt
- committers.cgi has been replaced with a custom 'committers' view
  at http://git.perl.space/perl.git/committers/
