Redesigned Webfrontend

Rewritten from scratch.
No longer using Google API for charts (flash), but flotcharts.org
(Javascript) which should also be compatible with most mobile browsers.
Added ability to hide or show information you don't need, e.g. chunks
and players on the same chart are not a good combination.
Enabled mouse interactivity with selection (click, hold and drag) which
will zoom into the specified region, added a zoom out button and a
dropdown menu for a quick selection of the timespan you want to see,
e.g. one week.
Added password protection.
