Invoke conversion script from the game binary about openage

[Qquanwei]

I agree,but now I can't find this file openage.convert >_<

[TheJJ]

The script is currently called by make media, which invokes the script located in py/openage/convert/__main__.py. The script is available as

import openage.convert

that's where the name comes from 😉

how should the game decide if it's necessary? how we deal with the game NOT reconverting everything on each run? should we have a sentinel file, like assets/is_converted?

[zuntrax]

I'm not sure what's the best way to do it now, but when we have nyan, we might just check if the main nyan file exists.

[TheJJ]

This will be done by #217.
