Added local blacklist and framework blacklist database synchronization

Local blacklist DB acts as a WriteThrough cache of the FW blacklist DB.
1. At the App startup time, the local DB is initialized with FW DB values.
2. A ContentObserver is registered to monitor FW Blacklist DB
3. Updates to local DB are also passed to the FW DB
