Move include directives for gst-libs into GST_PLUGINS_BAD_CFLAGS,
and fix all the Makefiles that use it. This is so that all the
include directories are added in the proper order: first the
directories in srcdir/builddir, then gst-plugins-base dirs, then
gstreamer dirs. If the order is wrong, installed headers may be
used instead of local headers and/or uninstalled headers from -base.
gst-camera is a gtk-test app to play with the imagecapture and videorecording.
gst-camera-perf is a tool to run various scenarios and take time meassurements
(e.g. shot-to-shot). Also sort the output files in configure.ac a bit to be
in alphabetical order.
