Add weight graph and preview

The weight data collection is manual, so we need a page for the user to input data, hence this commit isn't sufficient for a weight logging implementation on its own.
Weight doesn't have a dataChanged signal in sensorlogd, so that's currently not implemented here either
Because weight tracking isn't for everyone, the preview isn't shown by default.
