Kimmo Varis cfcfa3f000 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.

http://sourceforge.net/apps/trac/cppcheck/ticket/2849
Simplify: *d = b ? b : a; into if-else
Simplify { ; { ; } } into { ; }
Removed one memleak test which should be redundant now as question marks
should not get into memleak check.
