fixes #37 - Project detail bars. I've implemented an algorithm that calculates the
required number of backers for a task based upon the assigned importance, effort
and required resources. To get this working for the testharness I have had to
change the test data to be a random number between 1-5.
Projects can now be created and then they apear in the project gallery with the
correct bar sizes.
