Default badges for every reward tier

Currently the plugin creates a “Patron” badge, for the pseudo-reward-tier that has every patron in a campaign.

New campaigns in Patreon doesn’t have this “everyone” reward tier anymore, so the badge won’t work.

To ease the plugin usage I propose, that on every full sync, the plugin should create a badge for every reward tier and assign the badge for users in those tiers. The badge should default to off, so the forum admin can enable the ones he likes (icon, level) before enabling.
