- still tinkering with project save load, various js libs to enhance the overall ui etc
 * removed all "full" jquery ui package (including css & images) and replaced it with a bare-bones jquery ui version, with only what is necessary to make things draggable,
resizeable etc : this means no more weird conflict with bootstrap for things such as tooltips etc
 * lots of very minor updates and enhancements to the projectBrowseView : the complexity is way too big, to the point of not being managable, needs to be cut down drastically
 * a few minor fixes & improvements to the modal & dialog region helpers : added removable of the bootstrap "fade" class in dialogs, that were cause responsivness issues while dragging
 * added cosmetic changes to the projectBrowserView: custom sliders etc
 * added notification plugin & integrated it for connector login / logout notifications
- cleanup of the csg core :
 * deleted unused , redundant files
 * removed all old references to the CSG object/namespace (all handled with requirejs now)
 * removed the "csg" prefixes for file names (they are in the "csg" folder, so yes, they are related to the csg functionality)
 * fixed a few recently introduced bugs (2d geometry)
 * corrected some of the previous tests, added some new ones : all of them are still very limited (for boolean ops at least),
 as they only test the number of polygons/sides in the resulting objects
 * added tests for 2d (cag) operations & extrude
- a bit of general cleanup :
 * removed some of the now unused, very first , experimental files
 * removed a few deprecated files related to persistence views
