code action: create getter/setter for variable

[WebFreak001]

For code like int _foo;, create the property functions int foo() @property const { return _foo; } int foo(int value) @property { return _foo = value; }

• check if const can be used
• need some way to find proper place to put them in code (comments, other properties, convention, etc.)

This makes writing classes easier (snippets already exist, but this is more intuitive) and shows beginners how properties are created. The property should be added where other properties are. It could check the comments for “Getters”, “Setters” and “Properties” if possible, otherwise just put it after a block of members.
