Make it possible to view the raw output

Currently there is no way to look at the Cppcheck output from inside the IDE. You need to call it manually with the proper command-line options you get that.

We should provide an action which will show the whole raw output of the analysis for the current file similar to the Show Clang-Tidy Info action within CLion.

We should also make the --debug output available so it is easier to file upstream bug reports.
