Keep Ohmic losses constant while making adjustments to transformers, etc.

[LauraH]

Our team has observed that the DC and AC line losses we set can change when we work on a different parameter in the Ohmic losses tab.  We set the loss in %, but PVsyst has this tendency to recompute the wire gauge (or something) when we adjust the transformer losses.  If we use a number in percent, that's the number we want, not something recomputed for line length or expected current.  As it stands, we have to look carefully every time we exit the Ohmic losses tab.  

Incidentally, I'm not aware of any PVsyst run I've been involved with (mine, IE's, consultant's) in my career where the user has entered wire gauge or distance to calculate the loss, only %, so it's important that we be able to trust our settings to remain fixed.
