[PyQt] PyQt Licensing

[Phil Thompson]

First off, many thanks for not pestering me about this - it is greatly
appreciated.

In a nutshell, the PyQt licensing will not be changed in the short term.

This is mainly a financial decision - I want to ensure that PyQt
development, and that of other software, can still be funded. For the
moment an least, making an LGPL version available would be too much of a
risk - particularly as it would be impossible to reverse such a decision if
it proved to be a mistake - but it is something that I will continually
review.

I have made one change to the PyQt commercial license to address a
legitimate complaint. I have removed the restriction that prevented the
re-licensing of GPL code. In other words if you have a successful GPL
application and want to sell a commercial version then you can do - so long
as you buy commercial PyQt licenses before you start selling. To do this
you have to use the LGPL version of Qt as I think the commercial Qt license
still imposes the restriction.
