Add boggle_oo.js script

This is our in-progress solution for the boggle word-finder.  Our
current version (boggle.js) crashes if there are multiple instances
of the first letters of a word and some of those instances do not
result in the final word.

The goal of this feature is to take in a word and return ALL coordinates
for the word that exist on the board.  This version returns some but not
all of those instances.

This version is not integrated with the game_board and instead only
runs on a text version of the game.  We will need to fully integrate it
with the game once it is working.
algorithm seems to be working, needs more testing and refactoring.
remove unused methods and error-checking console.logs
Refactor object-oriented boggle code

Code is cleaner; console logs have been removed; unused variables have
been removed.

Code is now ready to be integrated into the game_array board, which
uses tile objects instead of the plain text board we used for testing.
