Feature/body uri param split (#203)

* Added support for specifying seperate uri and body parameters
* Added support for different message and handling generic types on socket queries
* Split DataEvent.Topic into StreamId and Symbol properties
* Added support for negative time values parsing
* Added some helper methods for converting DataEvent to CallResult
* Added support for GZip/Deflate automatic decompressing in the default HttpClient
* Updated some testing methods
