Add Long Term Statistics Board

Hi,

with the long term statistics you can collect the data, but there is no good board for having a look at these data, yet.
The statistics card for example does not support delta for showing data for day, month and so on for total increasing sensors and it is not easy to switch between the views (day, month, year).

There is already a great board for showing long term statistics data, the energy board, but this board is only for energy data…
So it would be great to have a board, like the energy board, where you can select your statistic entity and switch between different views depending on the date and time frame.

Thank you!
