make dillo compile with clang

* Variable length arrays are not allowed in C++. They are supported in
  C99 and gcc seems to accept them in C++ mode.
  Replace the few places where variable length arrays are used.
* The widget member in ComplexButtonResource was colliding with the
  widget member of FltkResource, so rename it to childWidget.
