Propper Formatting for Wiki Delta Tracking

This pull requests addresses [issue #5](https://github.com/alexames/DeltaBot/issues/5) by improving the formatting of DeltaBot generated content on wiki pages. It replaces old formatting with the formatting discussed in [this comment](https://github.com/alexames/DeltaBot/issues/5#issuecomment-25660920), includes tracking for the number of deltas earned in each submission, and changes spacing between items on the wiki page to make the page cleaner and more compact.

I have tested my code to the best of my ability, and it seems to work without issue. The next thing to do would be to create a clean-up script to go through all the wiki pages and update their formatting to fit the new standard.
