first attempt at adding a consistent css namespace

Unfortunately, it's not perfect... i.e. I've made some mistakes somewhere...

In any case, you can compare to genoverse.org here:
http://www.ebi.ac.uk/~dbolser/GV/Genoverse/?r=13:109600001-114364328

Just checking manually now (see the two new files for how I scripted it).


Cheers,
Dan.
Only if you change it in addDomElements in Track.Controller...

$('<div class="handle">').appendTo(this.label); -> $('<div class="genoverse_handle">').appendTo(this.label);
