c_str() all places where it is not needed anymore.
(I also add config.h to several files that was missing it)
+ added s string constructor to math_symbolinset
I also change some "while(" to "while ("
mmm ... yes ... I add a "zero()" function to LyXLength... an "empty()"
function did not seem appropriate. changed a couple of places that
checked on length.value() != 0.0.
