#3 gtkNode - wrappers for GTK+ 2.8.10 and various cleanups

[Romain Lenglet]

* src/get_inc_path
priv/generator/src/get_inc_path: reimplemented in
bash instead of tcsh, so that all scripts only
depend on bash

* src/check_otp: redevelopped using Erlang's
code:root_dir/0 and
code:lib_dir/1; now works all the time,
including when the "erl"
command in the PATH is not in the Erlang
installation hierarchy (e.g.
on Debian, erl is in /usr/bin, whereas the
Erlang root is
/usr/lib/erlang)

* priv/gen/gdk_generated-2.8.10.h
priv/gen/g_generated-2.8.10.h
priv/gen/gtk_generated-2.8.10.h: added generated
files for GTK 2.8.10
