Major Update:

- Implement consistent Function addition to application
  - Use TYPE_XXX constants to declare function type
  - Use NewXXXX() methods to call constructor correctly
  - Add FunctionType list (with constructor) to Application
  - Create Function by comparison to FunctionType list
- Simplify LoadConfig() and Init() methods for functions
  - Combine methods into Init() method
  - Pass relevant data member to Init() method
  - Remove all CDataMember references on functions
- ApplicationCore:
  - Split ReadParam() method from LoadConfig() method
  - Split main configuration into separate files:
    - config/ - main config file, general application settings
    - definition/ - application definition, e.g. function blocks
  - Definition and Address List files specified in config file
  - Load address file in address/ branch
  - Made DataTree & JSONparser private
  - Made Config, Definition & Address branches public
  - Removed unnecessary branch references
  - Improved event logging
- DataTreeCore:
  - Allow GetChFirstChild & GetChElement to create parent branches
    with correct type, ie. Object/Array
  - Remove unnecessary Create param from GetXxx functions
  - Bug fix: Print empty objects/arrays correct, ie. empty brackets
  - Bug fix: Adding element at specific index
  - Bug fix: Error when get/create string value with "null"
- FunctionCore:
  - Type param now set as constant via constructor
  - Create empty Handles & Channels objects if none in Config
- SelectableCore:
  - Add Queue length parameter to handles for UNIX and TCP sockets
- DeviceCore:
  - Bug fix: missing Process() method
