Fix crash when accessing the transaction code via post.xact.code using python

ledger would abort with the following error message:
  TypeError: No Python class registered for C++ class boost::optional<std::string>

The changes pass a CallPolicy to make_getter when adding the transaction
code property for python, so that the correct to_python conversion is
made. For details see:

New test data for increasing the set of possible tags.

I use more tags than just Invoice and Receipt, so I'd like this to support
more than just two.  Here's some test data showing other tags that I use.
Support a broader set of possible tags to be placed into the spreadsheet.

I've now made a hard-coded list of potential tags that are supported and
will be linked to in the general ledger spreadsheet.  This list should
probably be in a configuration file of some sort eventually, rather than
hard coded.

Indeed, note that the hard-coding goes into two different scripts, and
thus the lists could easily get out of sync.
MANIFEST output file that indicates which files are mentioned in general-ledger.

Due to reporting options given to ledger, not every file will be
referenced by the general-ledger spreadsheet.  The generated MANIFEST file
now indicates which files were actually referenced in the general-ledger.

The demo.sh script now uses this MANIFEST to create a zip file that
contains only those files.
Began fund-report.plx, which started as a copy of trial-balance-report.plx.

Fix ledger options and be sure starting is set to zero for new funds.
