* When a transaction aborts, add the error messages to the returned status to aid the development process (as suggested by @DeShadow)
* If we are an arangoerror log out the ArangoError code
* don't send the stacktraces via the 'net, but have better error messages anyway
* static is wrong here - we want to use it with per threads individual values now.
* restructure source just to have one stacktrace processing function.
* Pull array from javascript logging functions up to c++
* js_log now can handle an array of v8-strings, converts it to a vector of std::strings, feeds them one by one into logging for now.
* the stacktraces now don't do individual calls to js_log, but one with an array of log lines.
* fix query execution times that may have different between batches
* applied query statistic change to ui
* do not expose state "finished", as it is useless
