- more work done on ui cleanup and docking
 * almost there, docking east/west works 95 % of cases but still a few bugs to work out
 * visual (3d) views gets correctly "pushed" aside when docking/resizing docked panels
 * had to do some very "unclean" hacks to get it to work : views (very slightly) aware of other views outside their scope (visualEditor/ code editor) so
it need a big ole' cleanup
 * MUST move to LESS: css code is getting really unmanageable
blah
-fixed initial positioning of dialogs and docking system
- various css and styling fixes
more dialog improvements and fixes
 and yet more css and layout changes for dialogs
- various additions and improvements to the 3d view:
 * added experimental "structural" rendering (see through with hashed lines for backfaces) closes #97
 * better object rendering style switching implemented (shaded/wireframe/structural)
 * added settable positioning for grid numbering (center or grid border) , refactored/improved the grid helper : closes #96
 * fixed #95 : grid shadowing issue (was simply a spotlight (shadow caster) distance issue)
- some further enhancements to the dialog view and related changes
 * positioning of the dialog can now also be set
 * fixed collapsing of dialog issue when there is more than one dialog
 * dialogs are now actually closable (but not re-openable, yikes!)
 * re added display of hierarchy view
 * fiddling around with main menu items for various editors
