Add warning if no CAP installed but fix asset development costs > 0

[smartie2076]

A warning message should be implemented in E, when the development_costs of an asset are added to the NPV, but both installedCap and optimizedAddCap are 0. Then, the end-user can decide whether to remove the asset or not for future simulations.

The link to the comment doesn't work - at least for me..

So weird, it also happened to me with the constants in D2. Maybe one should not depend on review comments, which can be closed, for new issues?

Okay, that also did not work. Now, this is it:

• Development costs are costs that will occurr regardless of the installed capacity of an asset - even if it is not installed at all. It stands for system planning and licensing costs. If you have optimized your energy system and see that an asset might not be favourable (zero optimized capacities), you might want to run the simulation again and remove the asset, or remove the development costs of the asset.

I think a log message (e.g. warning) would be nice in this case.
