Mosby v3.2

• Enable Mosby to run when the platform is in Audit Mode (mostly for Dell systems).
• Update Microsoft SVN binaries to v8.0.
• Add a warning if the main Secure Boot variables haven't been cleared when running Mosby, since this can cause failures.
• Report NVRAM usage before and after using Mosby, and also warn if not enough space is likely to be available when writing a variable (#30).
• Add an option (--no-mosby-db) to disable the adding/creation of MosbyKey in the DB.
• Refactor some of the less used options into separate longform ones (--create-nopk, --no-log).
