85 cpp tests

[dimalvovs]

• fix outdated catch version;
• reverse the test compilation condition (make ON default, used to be OFF);
• add mechanics of calling cpp tests from within R;
• add possibility to use tags to call tests (for example to call groups of cpp tests);
• fix a bug that prevented configure to parse version from DESCRIPTION
