Added halt_compiler instruction for PHP <5.3 so it does not cough on namespaces. Moved logging function to an accessible block
Moved all plugin execution to a separate class without a namespace, so main file can be parsed in older PHP versions (well..to show the error message in a nice way)
Updated error messages during the health check. Added check for openssl extension (required by twitch)
Updated changelog, prepare release 1.4.1
