* simple testcase for file refresh (check for changes) and streaming reads
* add events for simple put and delete operations
* fix bugs in table filter events (type for first element was wrong)
* and I think a couple of other small bugs
* change internal reader interface again
* remove some quite embarassing bugs that must have been in the interface for rather long
* add different read methods to script & internal interface (like normal, streaming, etc). Not implemented in ascii reader yet.
But: there are still a few places where I am sure that there are race conditions & memory leaks & I do not really like the current interface & I have to add a few more messages between the front and backend.
But - it works :)
