asciitable 0.5.0

[Tom Aldcroft]

I'd like to announce the release of version 0.5.0 of asciitable, an
extensible module for reading and writing ASCII tables.  This release
features a new function to guess the table format from the supported
formats within asciitable.  This function is now called by default
within asciitable.read().

Other updates include:

- Added support for whitespace (tab or space) delimited tables by
setting
  the delimiter parameter to "\s".
- Improved support for RDB tables by parsing the second line which
specifies
  column type and (optionally) width.  These values are written out if
  available when writing an RDB table.
- More rigorous checking of format compatibility for several table
formats.

Tom Aldcroft
