Description of problem

At least for Qt Creator, the project name follows the name of the generated *.creator file (and associated files) rather than the directory name. So if pio project init always uses the basename platformio for generated files, all the projects will have the same name in the IDE.

Since there are now multiple files generated for qtcreator, renaming is tedious (though I can do it with a utility like rename).

Expected Results

Perhaps project init should name the IDE project files following the directory name.
