Refactor to how riot_API's main function is used.

Moved most functionality to a main() function as well as splitting
out the actually useful code pipeline for finding team name +
stats.
Update search resutls to return curated player stats for most recent game.

Index page returns wards killed/placed as well as damage dealt/taken.
This is shown in an unordered bullet point list. Currently the
search results do not show what champions were played, nor what
teams they are on. Things are starting to look up!
Change look of the index page via bar at top and heading changes.

Version number now at top, the welcome is more prominent than the
search.
