ToeTag BETA R3.0

Bugs Fixed  :(
==========
- Group Window does not close down after choosing an action button (like
  "View Exclusively") any more.  It was a feature, but it's now become
  tiresome to keep going back into the window.  I killed it...
  - This may seem like a PITA, but after clicking the action you want, just
    hitting ESC will close the window so it's not that big a deal...
- While viewing groups exclusively, if you added brushes/entities they
  would stay for a while and then disappear following a save (or other
  operation) because they are not a part of the groups you are viewing.  This
  was changed so that any items added to the map while only certain groups
  are visible, they automatically become a part of ALL the visible groups.
- If you deleted items from a group and hit save, the editor crashed.
- If you imported a fragment while exclusively viewing groups it would
  disappear.  It now becomes a part of all the groups you are viewing.
- *INTERNAL* - When importing a fragment it was pulling it's ID from the file
  and not using the one generated during construction.  This would lead to
  duplicate ID's in the map.  Not a good thing.

Features Added  :)
==============
- Keyboard Shortcuts
	"H"			- Hide Selected Items
	"Ctrl+H"	- Hide Others
	"Shift+H"	- Unhide ALL
- Hollow Brushes.  In the brush creation dialog, just turn on the 
  "Create Hollow" checkbox, enter a thickness and the 1 brush that normally
  gets created will instead be 6 brushes representing the outside of the
  area where the brush would normally appear.  This makes the creation of
  rooms and large areas extremely easy.
- Camera swing.  You can define in "File | Configure" how much the camera
  should move back when you are changing camera views.  This will help to
  keep the items you are working on in view at all times.
- Brush Merging.  Select all the brushes you want to have merged and press
  "M".  This deletes those brushes and replaces them with one big brush which
  encompasses the entire area the smaller ones did.  This is good for 
  simplifying your map ... getting rid of unnecessary brushes.  The less
  brushes you have in the map, the better it is (in my experience anyway!).
- Removed brush/entity mode.  There are no more "modes" in the editor.  All
  items are available for selection at all times.  The editor will act
  appropriately depending on which operation you perform (i.e. you can apply
  textures to selected entities and brushes but the editor will ignore
  the entities - duh!).
- *INTERNAL*.  Cleaned up major chunks of code, removed some things from
  the rendering pipeline to simplify it.
