Updated IndigoPlateau class and edited admin menu.
Updated to do list.
Improved indigo-plateau.php
Updated gitignore
Updated merge_players and some comments

The merge_players function is meant to edit mistakes when a player is entered
with two different names in the system, possibly due to a typo.

Some comments were added or updated. Lots of changes are still necessary, e.g.
will Indigo Plateau use some sort of automatic documentation mechanism? (It
should)
Shitload of changes

It's necessary to refactor the table_name code.

Must create a Player class to be able to use to_json correctly.

Fixed a small bug related to the $players array in the jsonify_player()
function.
Minor changes.
