In order to avoid parsing arbitrary python files encountered during
directory recursion, ``makesheets`` now checks each python file for a
string listing the *dungeonsheets_version* before trying to import the
character file.
- Circle now properly reflects the druid's available wild_shapes
- Unavaiable wild_shapes are not listed on the sheet but ghosted.
- ``spells`` is now longer relevant, only use ``spells_prepared`` in
the character file.
