Use OS paths (linux only for now), merging multiple paths. Init changes regarding options. Reorganised policies.txt a little. Implemented mde.resource.paths to read config from appropriate paths (currently linux only). Changed Init to load options before all other delegates are run and set logging level from options. committer: Diggory Hardy <diggory.hardy@gmail.com>
