Merge pull request #3 from acfung/master

Angus' third commit
Update README.md
Adding another data entry
Added basic logging support
Added basic logging support and started adding support for reading properties files.
Added support for caching and restoring seeding material for the KeyObjFactory to disk. NOTE: Looks like we have a bug; when I change contents of seed and iv on disk, generated keys are the same. Generated keys only change if I use a different secret value.
Fixed bug to properly store iv to keyfile and removed seed since we don't need to retain it once IV is created. Added /system/secret/setsecret and /key/destroyall
First commit for keyserv admin
