Fixed a lot of shadow warnings. Haven't actually turned shadow warnings
on, as there are a lot of warnings in dependencies. Also made some
constructors explicit, and tweaked the initialisers in some places.
This allows *.jam files to be treated as python files when importing and
including since the jam comment syntax is the same a python. This allows
us to write docs with b2 build files.
`value` doesn't track what a string is encoded as, and sometimes it's
plain text not boostbook. It would be nice to track the encoding and
automatically do the right thing, but I'm not sure if it's worth the
effort just now.

Because code blocks are added in sections, a nested section could be
unindented too far. Code is unindented in the main quickbook actions, so
there's actually no need to do it when extracting code snippets.
But this lead to left over whitespace that would have been stripped. So
change the `start_snippet` and `end_snippet` grammars to swallow up the
line they're on.
I also added a newline before the end of the snippet, this cleaned up
the occasional syntax error.
But due to these changes there is more leading and trailing whitespace
in the generated code blocks, so I just changed the code block grammar
to strip them out. This means there are no newlines at the beginning or
end of code blocks, but that should be fine.

Needs to store the version in the file object, since it's only known
after the file is read in, had to make files non-const. Put some checks
in to make sure this isn't abused but pretty messy.

Files are now permanently loaded. Quickbook substrings are stored as
references into the file. Now positions are stored as iterators into
the original file, the line and column is calculated when messages are
output.
This doesn't have much effect on efficiency but it simplifies a few
things.
[SVN r75253]
No longer stored in the iterator which means there's less messing around
with pointers and strings. Always stored as a fs::path which will help
with support for unicode. Also passed to outwarn and outerr as fs::path
so they can handle writing unicode filenames to the output.
