Important update:

- DataTree->GetStr return Member->Value or NULL if not found
- Rename DeviceCore EDataType to EMBDataType, avoid conflict with JSONpaser
- Add DataTree to FunctionCore with LoadConfig() method
- Change ProcessName to char * (from char[])
- JSONparse:
  - Rename RootPath to BasePath on all methods to reduce confusion
  - Allow FilePath to be NULL, add '/' if not present
  - Fixed Parsing sequence in ParseObject & ParseArray
