Moved leaflet code for map Itemview to views/Map.js and renamed class to Lizard.Views.Map
working on splitsing map to map, layer and popup
Merge branch 'master' of https://github.com/ddsc/webclient

Conflicts:
	app/scripts/lizard/lizard.map.js
Moved pieces of code to right locations, still need to fix all functionalities
add move option to backbone collection (for the moment in lizard.app.js)
add workspace as setting on creation of Map view
layer model is responsible for creation of leaflet layer (make it possible for creation of multiple types)
LayerList (must be workspace) sortable, including reordering of collection
Map has event binding with workspace changes (sort and reorder still todo)
renamed some models and views around layers and item views in lists
moved layer model to separate file
add DDSC layer to map
