v0.4.17

• Complete rewrite of the code,api desgin pattern ecc.
• For backward compatibility and integration with the Levels module, the new logic must remain bound to the flags already existing in the current module.
• Sync the status with the flags on the token, the checking of the visibility, if I can or cannot see the certain thing is currently bound to the values of the flags, with the new version for a better management of the thing each flag is associated with an AE, so if a token a l'active effects "Truesight" can see tokens that have the "Invisibility" active effects and that they usually shouldn't see.
• Integration with the DfFred Convenient Effects module with the will gonna be api
• Possible integration with perfect vision.
• Hope to have a multisystem integration, but for now PF2, DND5e are the first one requested.
• Possible integration with the levels it's seem to be the right road to follow, we can use the method overrideVisibilityTest(sourceToken, token){} of levels for override the levels visibility test.
