[Mozile] 0.8 Update

[James A. Overton]

	I've spent most of the last two weeks working through the  
frustrating details of insertion point and white space handling. This  
requires bridging the totally different Range and Selection systems  
used in Mozilla and IE, and accounting for many of the subtle  
differences between the Gecko and Trident layout engines. After many  
painful hours, I'd say the code is pretty solid now, but I'd like a  
second opinion. Please browse on over and try it out:

	Key differences to watch for:
- You can now move the cursor between image elements in Mozilla.
- New empty blocks (p, li) should be created and rendered correctly.
- The cursor should only move into editable nodes, and not the white  
space between nodes.
	If there's any behaviour that doesn't meet your expectations of what  
a rich text editor should do, let me know about it either on this  
list or at irc://irc.freenode.net/#mozile
	Many thanks,

James
