foreach loop formatting now obeys the line_length limitations

[MaciejPatro]

foreach(X IN LISTS aaaa bbbb cccc dddd eeee ffff gggg hhhh jjjj iiii kkkk llll mmmm nnnn oooo pppp rrrr)
    message("${X}")
endforeach()

now is handled as:

foreach(X
    IN LISTS
        aaaa
        ...
        rrrr
)
    message(\"${X}\")
endforeach()

• RANGE, IN [LISTS|ITEMS|ZIP_LISTS] keywords handled (still the old fashioned way)
• potential refactoring of foreach should be done with analyze command (in future)
• handling of line_length needs some more attention (break at the line_limit option needs more thought still)"
