JTextPane added to sidebar, glitch remains

Added the JTextPane to sidebar.  Even before this was added there was a
paint issue where the scoreboard and background of the game screen would
be painted to the sidebar every time the sidebar was
repainted/revalidated. I suspect it's arising from somewhere in the
Board class. Given that this occurs with the JTextArea as well, I think
it has to do with the sidebarPanel as a whole. Kept all the old code in
case we want to undo this.
JTextPane: No Glitch + More Thorough Commenting

Turns out the glitch only shows up on my machine so you guys should be
fine. Might be something we want to fix later since inconsistency
between machines is probably bad
Minor fix to sidebar

Proper text styling to alternate between red and white
Image Reformat

Reformatted images for background and instruction screens. Still really
not sure if this is the look we’re going for. Let me know what you
think.
Working Restart Button

Game will restart if you click restart game after game ends (won or
loss)
Added takeawaysPanel

Still need to hook it up to other panels.

Found a cool image that we can use on the takeaways panel.
