Added project management scripts.

The scripts/ directory will contain scripts that ease project
management.

build.sh prepares the project to be compiled right after a git clone.
There are a few components the application contains that are specific
to developers (e.g., public keys) and thus, these components cannot be
committed. Users can use build.sh to input there custom components and
then they should be able to build the application.
