enhanced source code editor widget

 Gtk2::SourceView2 is the Perl binding for the C library gtksourceview-2.0.
 This is the same widget that's used by gedit, MonoDevelop, Anjuta and several
 other projects.
 .
 This widget extends the standard GTK+ framework for multiline text editing
 with support for configurable syntax highlighting, unlimited undo/redo, UTF-8
 compliant caseless searching, printing and other features typical of a source
 code editor.
 .
