Adopting a challenge type layout from deckar01 (#399)

* Adopting a challenge type layout from deckar01
* Move standard challenge modals into the plugin
* Migration to change challenge type id to a string
* Travis testing now builds with MySQL, SQLite, and Postgres
* Rework get_standings to use the row ID instead of the saved time because of differences in database time precision
