Add support of basepath about yaade

[jonrosner]

FYI: This is actively worked on and will be featured in the next release

Fixed in the newest version. To use it, simply add the environment variable -e YAADE_BASE_PATH=/yaade when starting the docker container.

Could you give a quick example of how you would want this feature to look and what exactly you mean when you refer to base path variable?

[vchirikov]

It's impossible to start yaade from url like https://somesite.com/yaade/, it always trying to load assets from the root of site

[jonrosner]

Thank you for pointing this out. Will be investigated and fixed asap.
