Move Util::prior() and next() hitherto, and add Util::gtk_version_at_least() to do a runtime version check. * src/Makefile.am: Add miscutils.{cc,h}. * src/stringutils.h: Move prior() and next() into miscutils.h. * src/filebuffer.cc: #include "miscutils.h". * src/filetree.cc (expand_and_select): Use the lazy scrolling feature if GTK+ >= 2.1.4 is available at runtime.
