Respect 'Factor in Reload' preference for sustainable tank (tidied up).

[Neugeniko]

This fixes the reported sustainable tank for AAR and ASB. Resolves #1439 when used with the new capsim.

I did this fix in eso/savedata/fit.py. You can do it in effects but that involves overwriting the peak (reinforced) repair figures which I think should be shown all the time as the actual peak. If extrattributes were put in to hold sustained values then you could do the fix in effects without any down side.

Anyway have a play and see if it breaks. Comment welcome.

Looks correct to me. If you don't mind, I'll be pinging you if we get issues popping up about the cap stuff, since I've always looked at it going @_@. But what are doing here makes sense. :)
