Status line "Active Basal NS Care Portal" not working correctly

[andyrozman]

I configured multiple status lines, because I wanted to see more data, but it seems that most interesting parts don't work (correctly).

Active Basal - NS Care Portal - works ok if active basal is set, if TBR is running then I get weird reading (Nan% NaN). This should display either Active Basal or Active TBR.

So it seems that code doesn't work correctly if rate is in percent (like mine). It might work correctly if rate is absolute (units).

I fixed this and prepared Pull Request (#77).
