Adding gridlines display toggle shortcut. (#6313)

This feature existed in the original RCT1/2 games but was not present in
the latest development commit.

The original shortcut for this key was '7', placing it between the
"Invisible people toggle" (6) shortcut and the "Height marks on land
toggle" (8). This commit preserves as much as possible, using
placeholder comments that signify the relevant values which this
feature actually uses where this is not possible.
