Improves previous commit:
1. Initialise mIgnoreBase boolean member with FALSE.
2. Remove isBaseOnly() function and replace with direct use of Record member.
Adds a boolean setting to the user preferences. This setting is locally saved to all OpenMW-CS check stages. When a verification is done, the setting is updated on setup for each check stage. If set to true, the boolean value is then used to skip the verification process for every base record - minus some special cases where, e.g., counters are to be set first.
Related issue:
- Fixes#4466: Editor: Add option to ignore base records when running verifier (https://gitlab.com/OpenMW/openmw/issues/4466)
Tests:
The changes were successfully tested in OpenMW-CS by creating faulty "Base" and "Modified" records for every record type (if possible) and, then, running the verifier with and without the option respectively.
Also increased size of mSkills array to 7. Some factions with 7 skills can be found in the vanilla CS. The previously "mUnknown" int appears to be the 7th element of the skills array.
