[PyQt] ANN: PyQt v4.7 Windows Installers

[Phil Thompson]

The Windows installers for PyQt v4.7 GPL are now available.

Some notes...

- Qt v4.6.1 is included.

- Installers are provided for Python v2.4 and v2.5 as well as v2.6 and
  v3.1.

- MinGW is used rather than MSVC - so everything is much bigger.

- Everything is included for MySQL support - there is no need to also
  install the MySQL client libraries.
