This allows web sites to add some specific html headers to the pages generated by gitweb.
The new variable $site_htmlheader can be set to an html snippet that will be inserted at the end of the <head> section of each page generated by gitweb.

In fact, I used to insert the Google Analytics tracking code before </body>, but I recently noticed that Google is now recommending to put the html snippet at the end of the <head> section.
Here is the recommendation from Google: https://code.google.com/apis/analytics/docs/tracking/asyncTracking.html
From what I understood, the goal of putting the script tags just before </body> was to avoid to increase the page load time in case of latency of the remote server serving the js script. The GA tracking code is now loading the js asynchronously. So, it doesn’t block the page load anymore. So, the load can be started asap.

I changed this in the patch attached in this mail. Now the variable should contain directly the html code to be inserted.

I added the documentation to Documentation/gitweb.conf.txt. But, as I noticed that gitweb/INSTALL still exists and still documents the old variables, I left the doc of the new one.
