annotate mde/resource/paths.d @ 24:32eff0e01c05

Only locally-changed options are stored in user-config now. Log levels revised. Options sub-classes are handled more generically and can be added without changing the Options class. Options changed at run-time are tracked, and on exit merged with user options and saved. Revised log levels as set out in policies.txt and as used in code. committer: Diggory Hardy <diggory.hardy@gmail.com>
