Major update:

- DataTreeCore:
  - Bug fix: GetMember() error if member not found
- FunctionCore: (affected: SelectableCore, FileCore, WatchdogCore)
  - Made destructor virual
  - Standardize method parameter naming, e.g. pName, pLog
  - Renamed parameters: DebugLevel -> LogLevel, OutputDisplay -> LogOutput
  - Reinstated parameter BaseMember
  - Removed logging parameters from constructor
  - Created method InitLoggging() (shows "Function Created" message)
  - Split LoadConfig() method into parts:
    - Implemented public LoadConfig() methods
    - Implemented LoadConfigData() method, load parameters from DataTree
- WatchdogCore:
  - Derive from CSelectableCore instead of CFunctionCore
  - Rename parameter: PingTimeout -> PingInterval
  - Replace Ping Channel with Handle only
  - Add method SetInterval()
  - Send command direct to handle with (channel) Input()
- SelectableCore:
  - Rename parameters: Auto -> AutoManage, ReopenTimeout -> ReopenDelay
  - Implemented own virtual LoadConfigData() method
- DeviceCore:
  - Made all logging conditional: if (Log) Log->Message(...)
- SelectCore:
  - Renamed parameters: DebugLevel -> LogLevel
