Documentation fixes

A few things you might want to change in the documentation, specifically the main README.TXT file:

- Section 3.1:
- As there are more than 3 permissions listed, with no indication as to which the 3 'standard' ones are, I recommend changing "The Domain Access module has three standard permissions." to "The Domain Access module has the following permissions:"

- Section 4.2.2 (at the bottom):
- Correct "users with the 'view domain publshing' permission will also..." to "users with the 'view domain publishing' permission will also..."

- Section 4.3.4:
- Correct "Simple select the domain..." to "Simply select the domain..."

- Section 4.3.6:
- I can't see the option for 'Node Access Settings', so I assume this is what you mean by "this setting may be disabled." However, you state above (section 4.3) that "Some of these options may be disabled in the event that patches have not been applied." These options I can see, but they're grayed out. It seems there are two meanings to the term 'disabled'.
I recommend changing section 4.3.6 from "If you _are not_ using a module such as Organic Groups or Taxonomy Access Control, this setting may be disabled." to "If you _are not_ using a module such as Organic Groups or Taxonomy Access Control, this setting may not be visible."

Hope I'm not being too picky...
That's all I've found for now, will let you know if there're any more.

Also, I'm not sure if there's a way I can make these changes myself and submit them to you, let me know if there is...
Thanks!
