Change 3.0 to 3.00 in all version numbers, since NASM has
traditionally expanded all but the major version number to 2 digits.
Make the language related to __?NASM_HAS_IFDIRECTIVE?__ more
consistent.

There are currently six variations of each conditionals, and there may
be more in the future (e.g. %while). Stop trying to enumerate them all
everywhere.
Add support for index copying in the document processor.
Have pptok.pl auto-generate index metadata for conditional
preprocessor directives.

Make the source code for the documentation a little easier to deal
with by breaking it into individual chapter files. Add support to
rdsrc.pl for auto-generating dependencies.
