Tells project that it is in a git repo

Android Studio asked me if i wanted to do this.
Adds new exclude directory.

It is surprising that this wasn't in the original configuration.
Removes positive button from PlayerListFragment

The fragment will only have a cancel button at the bottom since
selecting a player will trigger the substitution action.
Re-adds new exclude directory.

I don't know what's going on. It definitely wasn't a remove in the first
commit.
Changes negative button to say cancel.

The negative button on the PlayerListFragment now says cancel and uses a
string instead of just saying negative.
Revert "Re-adds new exclude directory."

This reverts commit eea52b612098d7067c4df641493abf083bafb024.
Adds title to PlayerListFragment
Adds player_list_array

Creates a new array to hold the players on the team.
Changes PlayerListFragment message to player_list_array

Removes the test message from the PlayerListFragment and replaces it
with the items from the player_list_array.
Replaces hard-coded strings with string resources.

Specifically, the hard-coded strings in the player_list_array.
Adds public interface to PlayerListFragment.

This will allow the fragment to pass events back to the main activity.
Hopefully I can use this to switch the names on the button.
Implements PlayerListFragment interface in FormationView

Creates placeholder methods in FormationView for PlayerListFragment's
public interface.
