ANN: dbf version 0.92.002 released

[Ethan Furman]

Available at http://pypi.python.org/pypi/dbf

Fixed issue with Memo fields not returning correct unicode data.

Updated many docstrings.

Nulls now fully supported.

Getting closer to a 1.0 (non-beta!) release; working on PEP 8 
compliance, index files, and actual documentation.

Biggest change
==============
records no longer auto-update back to disk; make sure and use 
record.write_record() if you want the on-disk version of the table 
updated, or use the new Write generator which calls .write_record() 
before returning the next record in the table/list/index/whatever.



As always, comments and bug-reports appreciated!
