Enhancements

Rewrote and redesigned the process scheduler. It offers now a new REST API
Added functionality to define execution alerts via standard logging or via mail
Added new libs/ folder in the resource folder of the Job Agent. This allows to add custom libraries that will be available on the classpath during process execution.
The .RapidMiner folder of RapidMiner Server has been moved from the user space to the home directory
The Job Container now respects the defined JAVA_HOME of the related Job Agent and will use the Java binary from the PATH only as fallback
Added the possibility to disallow multiple sessions per user in the web interface which is switched off by default (this feature is not supported in high availability mode)
- Enable the feature by setting com.rapidanalytics.web.session.limit.enabled to true
- Set a maximum amount of allowed parallel sessions per user by setting com.rapidanalytics.web.session.limit.enabled.amount to any number higher than 0, default value is 1
