Editable unit settings

[pb66]

Not an immediate priority but it would be nice to be able to edit the "w" & "kWh" unit fields just as we can the currency field, Just a couple of "custom unit" fields that default to "w" & "kWh" would work, it wouldn't be necessary to have a list of alternative units as 9 times out of 10 the "w" & "kWh" will be used unchanged.

This allows the app to be used a wider range of data's eg water, gas and oil etc
