[ADD] depend on base_field_serialized to use serialized fields
[FIX] import from pyPdf
[FIX] don't pass list_class (which is browse_record_list anyway)
[FIX] don't assign to an active record's members. This causes database
writes
[FIX] remove deprecated string sizes, especially the one that is a
string itself and causes trouble in the ORM
Merge pull request #5 from hbrunn/master
