Removed left-over dependency to "validator". Added dependency to "async".
Added functionality to sync multiple entity sets with the remote database.
Unfortunately "boolean" is a reserved work and thus should not be used as a method. Renamed to "bool".
Removed unecessary variables from Cakefile.
Added unit test for database sync functionality.
No need for example #1 anymore thanks to the unit test of commit b70ee2fd323281757ff80b2621cfe91c477a6be1.
