TITANIC: Add game controls to help button

[dafioram]

The controls for titanic are mostly simple, but because of the non-standard controls of the star puzzle I believe its important to include the controls for that somewhere. We also have some additional buttons not in the original game. The help button in the gui seems like the best place to add this.

This way when users ask us the controls for this game we can then say "did you click the help button?"

I was thinking there would be three pages:
Page 1: General scummvm controls
Page 2:
Basic Movements:

Left Click: Move action
Shift + Left Click: Edit Chevrons and Quick transitions
Right Click: Edit Chevrons and Quick transitions
Roll Middle Button: Scroll through items (inventory,...)

Page 3:
Star Puzzle:

Tab: Toggle between starmap and skyscape
Mouse Click: skyscape star selection
Mouse Movement: starmap orientation
Z: starmap turn left
X: starmap turn right
' starmap turn up
/ starmap turn down
; starmap move forward
. starmap move backward
SPACE starmap stop movement
L starmap lock coordinate
D starmap unlock coordinate

If there is too much white space on page 2 maybe combine page 2 and 3.

The scummvm engine has controls added to the help button.

I also saw that the ctrl button is checked in titanic, but I don't think thats used for anything?

I didn't realize left click zoomed to a star when in starview so that would make the Mouse Click change to:
Mouse Click: skyscape/starmap star selection

Well, at the very least I'll copy the details into the README.
