Set version number and fix static access of qpMap
Add default test configs and remove unneeded test input file

This commit adds some default test configs, enabling us to run unit tests
locally in vagrant (you may need a 'sudo apt-get install sendmail' to get
it going.)

Also, this commit removes an input file that was used by a unit test to test
an encoding which we don't support (an encoding which wasn't supported by our
previous 4.1.1 version of SwiftMailer either.)

With this commit, pardot-5.0.3 behaves exactly as pardot-4.1.1 does with respect
to unit tests.
Updated .gitignore to ignore .idea directory
