Important Update:

Browse Source 
- SelectableCore:
  - Finish UDP implementation
    - Change UDPsock to UDPserver/client/remote
    - Add OpenUDPserver/client/remote methods
    - Add ReadFrom/WriteToUDP() methods (cannot write to FD)
    - ReadFrom/WriteToFD():
      - return negative bytes on error
      - small delay between consecutive reads/writes
  - Set address correctly on resolve (for UDP or TCP)
  - Improve ReadFrom/WriteToFD() methods (improved timing & error)
  - Improve error reporting on Input/OutputHandle() methods
- CharBufferCore:
  - Standardise ReadFrom/WriteToFD() method
  - Bug fix: Peek/PeekCopy error if Data param not passed
- FileCore
  - Standardise ReadFrom/WriteToFD() method
