[PD-dev] pd compiled for web with emscripten

[Claude Heiland-Allen]

Hi,

I updated it to Pd-0.50-2 (not updated the experimental Gem part yet).
Instructions remain the same, the changes are in the github repositories:
https://mathr.co.uk/empd

Example generative techno patch:
https://mathr.co.uk/dynamo/live to listen
https://mathr.co.uk/dynamo for info
https://code.mathr.co.uk/dynamo for source

Check the licenses for your libraries when making web pages like this, 
you might have to distribute the corresponding source code too.
