Functionalize competition setup

[slifty]

Adding a new competition to the development environment should be pretty cut-and-DRY (see what i did there). It's the same logic for each competition so far, with just a swapping of the competition name.

Lets replace the configuration.sh blocks for competition setup with a more generic function that is called for the various competitions our dev environment is meant to support. This will also make adding new competitions to our dev setup trivial.
