Adds `--output-deps` flag. To write out dependencies to `deps.txt`:
{{{
quickbook --output-deps deps.txt source.qbk
}}}
If `--output-deps` is specified, quickbook won't generate an output file
unless one is specified with `--output-file`. If there is an error it
will return an error code, but it will still write out all the opened
files.
Known issues:
- If the same file is included/imported twice it may or may not list it
twice. Should be consistent.
- Doesn't include SVG files. It probably should as they can affect the
output.
- Need to check some of the path issues for things such as xinclude
paths which depend on the output file path.
- Needs tests and documentation.

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.
[SVN r75260]
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.
