Improved GameManager printing to console

-Removed unused debugging output
-Added GameManager@LINE to the lines that were missing it
-Added output if a Tile/Bullet/BonusBox wasn't found.
-Removed .cpp from GameManger.cpp@LINE and removed semicolon after LINE
so that all output lines are the same.
Added missing files

-Forgot to add -structs/PlayerInfo.h
-Forgot to add moving ColorConfig.txt was from media/ to config/
Updated .gitignore

-Ignore all .html files and TODOList as these aren't source code related
Added setting of prev pos in Bullet

-Sets oldRect's y value in Update(). Only y is needed to be set, since
x won't change once the Bullet is fired and width/height is always the
same for all objects.
Improved Server output

-Changed send output to use TCPMessage::Print() so that the message will
be printed properly and added the connection number it was sent to.
-Added ouput for messages printed to all clinets.
