For clarity. In so doing found the backend behavior a bit inconsistent
so it's modified to do what the enum values indicate.
In the course of changing the various calls I found some implementation
errors in the back end and corrected them.
It's more descriptive and less likely to be confused with the book:id value
in XML files that is the book's GUID.
Also changed the QofSessionImpl::begin new_uri parameter from std::string to
const char*. There's no point in allocating a string just to call
new_uri.c_str() all over the place.
It is split into
- /libgnucash (for the non-gui bits)
- /gnucash (for the gui)
- /common (misc source files used by both)
- /bindings (currently only holds python bindings)
This is the first step in restructuring the code. It will need much
more fine tuning later on.
