Important Updates:

Browse Source 
- DataTreeCore:
  - Allow types float, int & bool to be read as strings with GetStr()
- LogCore:
  - Add comments to Logging parameters
- WatchDogCore:
  - Call CSelectableCore::Process() in Process() to manage connect
- SelectableCore:
  - Allow SetSocketHandle() to be called if Handle already set as socket
  - added strlcase() method to convert string to lower case
  - Update Handle structure:
    - renamed Address -> HostName
    - renamed PortNo -> PortName
    - added AddressList for all resolved addresses
    - added AddressInfo for active address
  - Add ResolveAddress() method
    - Domain name and protocol port resolving with GetAddrInfo()
  - JSON updated:
    - domain name can be provided instead of IP address
    - protocol can be specified instead of Port No, e.g. "HTTP" / "SSH"
  - Resolve address before connect, or use next resolved address
