Tom Brown 658f8ad00c Distribute existing power plants to the correct nodes
Previously they were distributed only by country to the first node in
the country.

Now conventional power plants are assigned to the correct node using
the bus map from PyPSA-Eur.

Wind and solar are distributed in each country by capacity factor.

The code has been refactored and a bug was fixed whereby total
capacities of wind and solar in each country were not correct.

Now the years in the config.yaml for myopic are integers not strings.
