Major update:

- General bug fixes
- Implement search for multi-character marker search in BufferCore
  Replaced FindChar() method with FindStr() method
- Implemented LocalIO and LinkedIO in FunctionCore
- Connect LocalIO with FD in SelectableCore
- Implement Write buffer with Write Select in SelectableCore
- Improve validation checks in SelectableCore
- Use Handle ptr instead of Handle Names for Config methods
