Removed pluginType : "dialog" which seems to have been showing two windows on MAC, tested on an old one and no longer displays two.

Added property score to window object to record the score the plugin is working on.
Added title to window to make it obvious which score the text belongs to
Changed from Keys.onPressed to Keys.onReleased as in some circumstances the last keypress was lost.
Added onActiveChanged to window object to check if the score has changed, If it has, the text and title are changed as appropriate.

Great work. I will merge it as it.
For your next contribution in this project or others, some git etiquette. No need to add comment with your name in the code. Instead, use proper commit message describing in one line what you changed in that given commit. If some commits are related, squash them together http:https://gitready.com/advanced/2009/02/10/squashing-commits-with-rebase.html
