Add feature to take notes on players

[justpokerdev]

Some poker apps allow you to takes notes on players at your table. It would be good to add this functionality to JP.

There could be an additonal entry in the player menu (shown above) "Notes", that when clicked opens up a movable text box (shouldn't cover entire screen and shouldn't stop you from interacting with the rest of the app), where you can add text.

Text box should also include "Save" and "Cancel" buttons to either commit or discard changes.

Notes are private, and only the player taking the notes them should ever be able to see them. Notes should persist after a browser refresh (need to be stored in backend as well).

I will add this feature

You should also be able to view/take notes on multiple players at the same time, and resize the text area. The text area should be semi transparent, with an opaque border. I'm also thinking a little "X" at the top right to close it.
