SCUMM: Implement original pause bars, and put Save/Load GUI type toggle in startup menu

[ATMcashpoint]

Basically, none of the SCUMM games from Maniac Mansion to CMI have the proper "game paused" effect implemented. Instead, they all pop up ScummVM's own custom "game paused" bar, and also make the screen brightness dim somewhat (an effect not in the original games).

I propose that ScummVM should allow the emulation of the various original "game paused" bars. If it's desirable to keep the current "house style", then there should be an option to switch to the original pause-bar style in teh startup menu.

Note that different games' pause bars have different associated effects: eg, in Maniac Mansion and Zak the "Game paused" text is actually on the Sentence Line, and the cursor becomes an image of a snail, while in CMI the text & background colors of the pause bar change based on the current background.

Also, the Alt-F5 key allows you to use the original Save/Load GUI for SCUMM games. However, SCI games have a checkbox to enable this option in the tabs in ScummVM's startup menu, which is much more convenient. It'd be nice if this was replicated for SCUMM games too.
