Add support for "robots" meta-tag

With this change, cgit will start to generate the "robots" meta-tag, using
a default value of "index, nofollow".

The default value can be modified with a new cgitrc variable, "robots".

 ## The "Idle" column on the repository index page can read a timestamp
 ## from the specified agefile (if this file cannot be found, the mtime
 ## of HEAD is used).
 ## The cgit repo on hjemli.net uses the the following command in it's
 ## post-receive hook to update the age-file:
 ##   git-for-each-ref --format="%(committerdate)" --sort=-committerdate \
 ##     --count=1 > $GIT_DIR/info/web/last-modifie

 #agefile=info/web/last-modified
 
 
 ## Git detects renames, but with a limit on the number of files to

 ## Specify a root for virtual urls. This makes cgit generate urls like
 ##
 ##    http://localhost/git/repo/log/?h=branch

 ## instead of
 ##
 ##    http://localhost/cgit/cgit.cgi?url=repo/log&h=branch
 ##
 ## For this to work with apache, a rewrite rule must be added to httpd.conf,
 ## possibly looking something like this:
 ##
 ##    RewriteRule ^/git/(.*)$ /cgit/cgit.cgi?url=$1   [L,QSA]
 ##
 ## For this to work with lighttpd, the rewrite rule should look more like this:
 ##
 ##    url.rewrite = (
 ##        "^/git/([^?/]+/[^?]*)?(?:\?(.*))?$" => "/cgit.cgi?url=$1&$2"
 ##    )
