Website page on SVN could use some more details

[dtgriscom]

The page at http://dojotoolkit.org/community/usingSubversion explains a lot about how the repository is organized. I suggest adding some more information:

• All releases will be found inside ​http://svn.dojotoolkit.org/src/tags/ , where each item contains a complete release

• The special views each lead to a page with a single README that contains useful information. Its contents should be copied into the usingSubversion page. They are:

This is the ALL view, it includes all of the Dojo Toolkit packages. This currently consists of:

	dojo/ (the core) 
	dijit/ (the Dojo widget system)
	dojox/ (additional Dojo-based components)
	demos/ (the demos for use on dojotoolkit.org)
	utils/ (the build system, doc system, and additional resources)

When viewing this tree from ​http://svn.dojotoolkit.org/src/view/anon/all/trunk you will not see any of the available files. Each project above is using an svn:external pointing to it's trunk folder.

For instance, Dojo Core repository is: ​http://svn.dojotoolkit.org/src/dojo/trunk

There are two versions of this view: anonymous and committer.

For users (readonly): ​http://svn.dojotoolkit.org/src/view/anon/all/trunk

For committers (read/write): ​https://svn.dojotoolkit.org/src/view/committer/all/trunk

I think I've captured all of these changes as well. Will go live this weekend.
