Pakage rename

[bletham]

Rename fbprophet to prophet.

Make fbprophet a shim package that just imports prophet. Any code currently importing from fbprophet will continue to work, but will get a warning message that they should update to use the prophet name.

Update all of the notebooks to use the new package name.

I'll wait until after it is pushed to pypi to update the markdown documentation and references in the website.

Testing

Check that all references are changed:

grep -R fbprophet *

Check new prophet package works:

Uninstall prophet and fbprophet:

pip uninstall fbprophet
pip uninstall prophet

Make sure they're gone:

import fbprophet  # ModuleNotFoundError
import prophet  # ModuleNotFoundError

Install prophet and check that it works:

cd python
python setup.py install
cd prophet/tests
python -m unittest

Check the shim works:

cd ../../../python_shim
python setup.py install
cd fbprophet/tests
python -m unittest

Final check by running all notebooks with updated package name

All successful

tested. Both shim and the new package work fine and pass all tests.
