Albrecht Schlosser a7a1e1594c Fix stale current_ pointer when deleting Fl_Group
If a user program accidentally deletes the "current" group, then
the pointer would still point at the deleted widget. This commit
prevents this and makes the Fl_Group's parent the current group.

Fixes issue #88.

README - Fast Light Tool Kit (FLTK) Version 1.4.0

WHAT IS FLTK?

The Fast Light Tool Kit ("FLTK", pronounced "fulltick") is a
a cross-platform C++ GUI toolkit for UNIX(r)/Linux(r) (X11),
Microsoft(r) Windows(r), and MacOS(r) X. FLTK provides
modern GUI functionality without the bloat and supports 3D
graphics via OpenGL(r) and its built-in GLUT emulation. It
was originally developed by Mr. Bill Spitzak and is
currently maintained by a small group of developers across
the world with a central repository in the US.
