* src/main.cc (RegexxerOptions): Make init_state_ a value member
of the class instead creating it dynamically.  This simplification
is now possible since the RegexxerOptions object will be allocated
dynamically anyway.
(RegexxerOptions::init_state): Rename from take_init_state(), and
make it return a const reference.
(main): Use new init_state() method when initializing the window.

* src/mainwindow.{cc,h} (MainWindow::initialize): Change init
parameter type to a const reference.
