add granularity to IDE folders

[headupinclouds]

Currently library modules are built as static libraries and CMake adds "Source Files" and "Header Files" folders like this:

module
 |-- Source Files
 |-- Header Files

It would be nice to include an addition folder for subcategories, such as the gpu modules.

module
 |-- Source Files
 |-- Header Files
 |- gpu
      |-- Source Files
      |-- Header Files

Are we talking about source_group here?

@ruslo: Yes. Thanks. I'm not sure how this behaves in combination with set_property(TARGET ${library} PROPERTY FOLDER "some/module")

Don't know, need to try. I was thinking about automatic groups creation long time ago. Worked something like this:

• https://github.com/ruslo/sugar/wiki/Generating-groups

There was a Python module for generating CMake code. Too tricky, now I think it should be done in CMake itself :)

Current IDE layout w/ source_group is working well enough for now. This is represented in #88.
