Add text annotation tool

[StoneT2000]

Let user annotate onto the game with text. There are two places. Putting text into the map, syntax then could be

text(x, y, message, fontsize)

There could also be text on the side, syntax could be

sidetext(message)

This would be on the side in a two column thing
