Move Suppressions class to own source files.
...
I want to use Suppressions class also in GUI. And that is easier
to do when it is not internal class of Settings class. And in
general is it more natural that Settings class only contains list
of suppressions and implementation is separate.

Add command line option: --debug-fp ... If used, cppcheck will print out the code generating error into output stream.
...
This is ment to be used for debugging false positive errors in Cppcheck.
Current implementation tries two alternatives. Without all headers or with all headers and prints out the option with
less code. In future versions this could try with individual headers or group of header files.

Use "enabled" list for the style checking.
...
Settings-class currently enables style checking via dedicated
boolean attribute. All other CLI's enable-options are handled
through the enable-list. This commit moves style-check enabling
to use the enable-list.
Main advantage is the consistency how options are handled/stored
in the Settings class. Which also unifies using them for the other
code. You need to enable certain type of checks? Use the
addEnabled()-method. You want to check if certain type of checks
are enabled? Use the isEnabled()-method.
