#1 Support reading Falch.Net PDB files

[Paul Gilbert]

Falch.Net created PDB files can't currently be read by
the PDB access component - they don't have an extra
padding byte in them which the Palm Specification
includes (albeit not absolutely mandates). Need to
rework the component to use the offset table to work
out where the data starts, rather than relying on it to
follow immediately after a padding byte
