Major Update:

- Updated all Logged messages, standardised DebugLevel:
  - dlNone   - Show startup and stop
  - dlLow    - Show creation/destruction of Function Blocks and Local IO
  - dlMedium - Show connection events, eg. open/close
  - dlHigh   - Show data flow events
-LogCore:
  - LogMessage and ShowOutput uses va_list
    only run printf if DebugLevel correct
  - Remove global LogStr[] variable
- SelectableCore:
  - Implemented Auto-management of handles
    auto open on startup/fail/close
  - Changed simple Open/Close/Read/Write methods to inline
  - Do not set Select Write trigger for server socket
  - Memory leak, setting address twice on RemoteClient
  - Bug fix, only send handle out data if DebugLevel = dlHigh
  - Bug fix, do not Read/ProcessBuffer if no InputBuffer
