Manage Meter Readings

[careck]

There should be two ways in which meter readings can be managed:

1. from the meter list attached to a household
2. from /bend-electricity/listmeterreadings

When accessing meter readings from the houshold meter list, we see all readings in chronological order for that meter.

When accessing meter readings from the electricity main page, we first see all electricity periods and then when selecting a period we see all meters from all households for that period in order of the household street number.
