v0.9.0

• Added a new role that can be assigned - "Independent". This role doesn't have any positional rotation, helpful if you are e.g. burning one of the bosses and don't need DPS to follow one of the built-in rotations. Due to this new feature, this update is not backwards-compatible - everyone in the raid must update.
• Raid layouts can now be saved globally across all your characters and can be named so you can set up multiple for different raid groups / strategies.
• You can now opt out of the staggered Zeliak positioning for healers and instead treat it like the other corners.
• Added an option to change the out-of-date version warning popup to a chat message - thanks to @mhco on GitHub for the PR!
• Window positions are now saved per character.
• The map and raid config windows can now only be opened by raid leaders/assists when in Naxxramas.
