When adding new items(methods, fileds, constructors etc.) through Add.. function
of Explorer's pop-up menu, the code should be pasted inside editor more
intelligently. Current state is that everything is pasted to the end.

- group items, so for example methods would form a block of code.
- private,protected,public or friendly members should be also grouped together.

This formatting could be also made by "Reformat Code" (Ctrl+Shift-F) function.
