Grouping sources and headers feature

According to one old occasionally (in our opinion) closed suggestion QTCREATORBUG-1053 (https://bugreports.qt.io/browse/QTCREATORBUG-1053) created 04/Apr/10, Dmitry Rekman wrote:

This additional level of hierarchy (Source/Headers) is inconvenient. I expect similarly named files (whatever.h, whatever.cpp, whatever.inl) to be close to each other in solution navigator sidebar, but right now it requires me to keep the same directory structure opened twice.

Just add an option to show files as they are physically on the disk, without any additional segregation.

According to ours skills and practice of using Qt Creator we found this suggestion very useful (except of one moment -- we insist on ignoring forms. Sources are .h/.cpp, but forms is a bit another).

That's why we recommend to reopen this issue and take into account ours approach to reach this functionality.

Our fix affects current master of qt-project.
