dApp - alternate update message according to version changes

[weilbith]

Description

When a version update includes breaking changes, mostly by new contracts, the user must be informed about that and should first take action and withdraw all funds from the old contracts before updating. Other updates can be just applied right away.
Therefore we need an mechanism that allows the dApp to categories updates to alternate the message and appearance.

Why do this?

Better inform dApp users when changes involve contracts and state migrations. So that they are aware when contract moves happens and old state and channels get obsolete.
