hawken 3701ce4037 Eliminate some compile warnings (#600)
* Remove some unused variables
* remove duplicate "using .." by sorting and deduping the list
* Remove things that already exist in the parent class (in one case I moved some documentation to the parent)
* EntityBodyData and and NextSearch were never set (only read), removed
* _timeout was never read, subsequently _timer became unused. part of a TODO timeout functionality that was not implemented yet
