Carl P. Corliss 629efb6057 Fixes LoggerSilence#silence threadsafety
- uses instance defined level if no custom local log level defined
- Keeps track of local log level per [ thread + object-instance ]
- prevents memory leakage by removing local level hash key/value on #silence method exit
- avoids the use of Thread local variables
