Add doc building scripts into the disc
The doc building process is not easy but can be greatly automated.
Providing some scripts in the VM can help to reproduce in a contained environment.
I lately got some issues with configurations ( old installation going down, transifex not working one the alternative OS). So a few scripts can help prepare things in a well known place). I also don't know how to package
- install dependencies
- configure environment
- download github repo
- update strings from Transifex
- update po files in GH and Transifex
- build and clean the docs (image resizing, file paths, ...)
- package the docs
