Restore the option to put a Multi in pass-through / inverter mode

[mpvader]

Using VE.Bus firmware 414 or earlier, in combination with a Venus device, it was possible to set the AC input current limit to 0A. A trick, to which the Multi responds as follows:

• PowerAssist enabled -> Multi switches to "inverter only"
• PowerAssist disabled -> Multi switches to "pass thru"

When using the old Digital Multi Control panel, exactly the same happens.

This feature was removed as part of the 415 improvements in on/off & input-current-limit settings. More about that here

There are various options to restore it; to be discussed.

@vejpasop can you do this? Or does this require changes in multi firmware? Or should we do something else?

Or asked differently: how do you suggest we solve the whish from customers to force a unit into inverter mode?

Tip from JEroen: one solution is dropping the "readonly" attribute on the Inverter only option in the pulldown.

Exactly that would solve it. Writing value = 2 to the Mode path forces the Multi in inverter mode
