Update and fixes.

Hi,

I liked your work on this template for Munin. I cleaned it and made some improvements, some code cleaning and fixes:

* Removed unused files (css, js...).
* Code cleaning and refactoring.
* Fix and clean all html code.
* Bootsrap integration on comparison pages.
* Fix domain/host trees in html lists.
* Fix bootstrap uses (eg. responsives row and cols instead of html tables, navbar...).
* Fix bootstrap tabs and html anchors links.
* Fix bootstrap responsiveness, add responsives features to all graphs.
* Many others tiny fixes.

I added an installation procedure to the readme file too.
