District_EMS_Controller

[Hoppe-J]

just a small implementation of a list of "used" outputs of ems component.

Problem was when simulating an ems on district level with 2 households which should recieve the same amount of surplus electricity and households have the same tags and sourceweights in connection with ems. The target output of the district ems is just working for household 1. This is due to the functions "sort_source_weights_and_components" and "get_dynamic_output" in ems_controller modell while searching for outputs based on tags and sourceweight. With the "new" list, outputs are saved and can't used twice.

Add a new compononettype for defining surplus in districts
