List of checks does not give enough flexibility to
select/unselect specific checks. The tree fixes that.
Also remove Clang-Tidy checks line edit because it is
now integrated into the tree mode as an alternative way
of providing checks by pressing "Plain text edit" button.
'cpptools_clangtidychecks.h' is generated using python
script 'generateClangTidyChecks.py' and clang-tidy
from our LLVM/Clang 6.0 build.
