Add test block objects to database for use in create-dashboard dropdown

[daniel-schroeder-io]

I created an example of how to complete this in pull request #152

create-block.html has an example on lines 11-15 of how to use AngularJS to populate a select
then there are functions in the block-controller and block-service js files of how to do database retrieval

This sort of pull and populate functionality needs to be applied to all forms for (blocks, dashboards, and stories)
