Make Reflection caching more intelligent
The Reflection Service caches all the reflection information. If a class is altered, the cache is not automatically cleared because FLOW3 just doesn't know about it - the reflection information becomes inaccurate. Furthermore it is only possible to flush the whole reflection cache and not only the information related to a specific class.
We need some File Alteration Monitoring which automatically monitors all class files (in development context) and flushes the relevant parts of the reflection cache if classes are modified.
