Changes summarized in comment

Here are the changes I made:

I deleted the definition of "Legal Entity". This makes it easier and cheaper to bring corporate entities into compliance with copyleft-next; enforcement through litigation won't need to delve as deeply into proving how an the infringing corporate body is governed.

I alphabetized the first Definitions list.

I corrected the numbering of the Sections in the license.

I capitalized Section to improve readability.

Section 4: deleted parenthetical phrase "to the extent they remain pertinent". Allowing code recipients to delete Legal Notices as long as they meet a vaguely worded obligation could encourage circumvention of copyleft-next.

Section 6: Made an effort to address the FIXME. 

Section 6: Added a notwithstanding statement to paragraph 2. That would make the license a lot simpler for developers who want to know quickly whether or not the license is GPL-compatible.

Section 7: attempted to clarify what I understood to be an exception to the URL requirement

Sections 9 and 10: changed Section numbers referenced to ones I believe were intended to be covered.

Section 12: added statutory damages to the list of liability limitations.
