Ship_info and Upgrade_info in python do not apply factors

[royfalk]

With the introduction of #895, the configuration in C++ has factors for reactor, capacitor, ftl_capacitor, etc.
When displaying their properties, these factors need to be applied.

However, the code we are using in ship view to transfer the ship stats is the same code as save ship to file. This applies the factor in reverse, or multiple saves would apply the factor multiple times. We need to expose these factors to python by porting them to config.json.

The same applies for upgrade view, where the configuration is read directly from units.json.
