The attached patch allows to use \n to include newlines in strings
enclosed in double quotes read by the airstrike shell. The change is
inside the chop_str() function.

Example:
"msg=This is on line 1.\nAnd this on line 2."

Since display_text() already knows how to handle strings with newlines
this enables us to show multiline messages from e.g. triggers.

If no one objects I'll commit this to svn soon.
