Subject: luci-app-battstatus: initial release

Introduce a new package luci-app-battstatus which queries battery charge
information using i2c commands and displays a charge indicator in the
upper right notification area.

So far this package has been tested to work with the HooToo HT-TM05
travel router but might be extended to cover further models in the
future.
