Everything running

This pull request add the python file that runs all the process to update monthly the WDPA.

You just need to run monthy_update.py to do that.

All classes now have parameters that are stored as variables in the above file. I f you need to change passwords/directories/buckets please change them on monthly_update.py.

Readme file was updated to explain the whole process and how to set up the server

I note that `wdpa.sd` is gitignored, should this file be ignored as well?
