Added rake tasks for project management.

Rake tasks will help in automating and maintaining various parts of the
project, including initial setup of a freshly cloned repository, running
command-line compile and testing commands, and any other task that is
required in the future.

These scripts are built on top of most of the command-line functionality
provided by other tools, such as android, ant and mvn.
