Fix error for mongo BSON document limit

*Added FiFo-Array as dependency to handle to many requests on a single bin
*Added propertie file to define max size of requests per bin
*Set default max size of requests per bin to 100

(at about 10.000 requests per bin parse error triggered when requesting bins)
On line 133 the request is added again. If I'm not mistaken you will end up up with a duplicate of the request.
