Give the modules settings its own tab

This moves the module settings into its own tab instead of grouped with the hardware configuration page.  The later was pretty weird since the only commonality is the fact they are settings that apply only on power up.  This also means that trying to save the hwsettings doesn't result in a lot of failed transactions.

Once this is merged, I would suggest we consider moving the other tabs such as CameraStab, TxPID and Autotune into this general module tab.  We can show only the widgets appropriate based on what is in ModuleSettings on power up.
