#289 fix + application servers compatibility

[IngvarJackal]

• fixed new Fiber(FiberScheduler, SuspendableRunnable) scheduler is not passed #289
• made JMX loggers more robust -- they won't fail but simply re-register MXBeans in case of redeployment to wildfly
• made default MXBeans use prefix from quasar.properties java property file from package resources to be able to deploy multiple packages with quasar to an application server (wildfly). Made rest of properties (co.paralleluniverse.*) overridable from aforementioned file too for separate package configuration.
