#20 system view added
- log of app and system added
- reused system panels and edited home to use that
- new service method for system state - get app and system log
- new log4j appender rather than accesing the file created by the app
  directly - was not always finishing, sounds odd to log to a file and
  then read from it
- not nice accessing the in memory appender directly via static method
- runtime executor ammended to allow executing and retrieving strings
  directly
- tests pending
