c_profileAssets on the GC canvas, should contain all consumption and production assets aswell. + c_fixedAssets collection should be added

[AteZenmo]

• create c_fixedAssets on the GC canvas that contains all fixedAssets.
• J_EAConnect should be revised to make this happen
• J_EARemove should be revised
• f_operateFixedAssets can become one loop over c_fixedAssets.
• Careful: Heating managements check both consumption and profiles! Change this to only profiles
• Careful: Battery strategys make prediction based on consumption and profile assets (Mostly project specific, so not this issue, but a warning for colleagues would be nice).
• Careful: Zero Interface checks in certain functions for consumption and profile assets aswell (savings sliders, getPeakHeatDemand, etc.)
