formatted copyright file errors

Hi,

The debian/copyright file is formatted (per draft Dep5) but has errors respecting the current version of the spec. (http://svn.debian.org/wsvn/dep/web/deps/dep5.mdwn?op=file&rev=135). It is marked invalid by my copyright parser and therefore licenses and copyrights cannot be reliably extracted.

I'll attach three items:
 * a report of the copyright generated by my copyright parser. I generated this after fixing the copyright's first line so that it is recognized as formatted. This shows that many of the errors are in using free form text in "License: " lines, which is not allowed. Spaces delimit license assertions. Every asserted license must be either defined in place, or have a free standing stanza to define it, or be a well-known short license name per the spec. Because "NONE" is asserted as a license, I added a "License: NONE" free-standing stanza whose text indicates that no license is asserted. I also added a GPL-improper stanza (reluctantly) to handle this case, which needs review. Also, every "Files: " stanza MUST have a "License: " line (a required field), even though that seems redundant, but this aids readability.
 * report of the copyright generated after I fixed it.
 * a bzr diff that contains the fixes.

Please review changes for accuracy and apply.
