Missing features in menu graphics (difficulty select & level select)

[Gagert]

When comparing the difficulty select menu in the original MS-DOS release of Jazz 1 to OpenJazz, there are some differences that can be found in still images itself of those menus:

MS-DOS:

OpenJazz:

Now the level select screens:

MS-DOS:

OpenJazz:

The blueish main menu animated background is missing in both OpenJazz's level select & difficulty select menu items.

The animations or could you say fading-effects for the menu items in both the level select & difficulty select menu are also not present as of yet in OpenJazz.

Thing here is, drawing stuff not a text or image (so lines, boxes, etc.) is just not implemented in OJ.
The plasma effect currently only works on the main menu and would look ugly without the added box behind the options.
I added a commit to use the actual episode names though.

About the animation between the difficulty levels: There seems to be some kind of analysis of the current pixels and then they are reordered to the new image, no idea how it is done in the original engine. So, this effect is not implemented either.
