Background
We want to allow people to use the extension even before they add a subscription to their Flattr account. Thereby they can discover what the extension does without any up-front investment.
What to change
Stop considering whether account has active subscription when checking whether extension should be active
Stop overriding icon state to indicate an error when there's no active subscription
Move existing message which informs the user about the lack of a subscription to replace the "beta" box in the icon popup
Replace the message's body text with "Keep in mind that without an active subscription, your favorite creators won't receive any money from you. Any flattrs made without an active subscription will not be converted into money."
