Remove the use of g_type_init() because it has been deprecated.

	* codegen/extradefs/generate_extra_defs_atk.cc: The docs for the
	function says that the GType system is initialized automatically now
	as of glib-2.36.
2.22.7
Atk::Text: Deprecate get_text_before_offset(), get_text_after_offset().

* configure.ac: Don't treat the deprecated-declarations warning as an error,
not even when --enable-warnings=fatal.
* atk/src/text.hg: Deprecate get_text_before_offset() and
get_text_after_offset() and the corresponding virtual functions. They have
been deprecated in atk. Bug #703027.
Add the generate_defs_and_docs.sh script.

* codegen/generate_defs_and_docs.sh: New file. Script that generates
atk_docs.xml and most .defs files.
* codegen/Makefile.am: Distribute generate_defs_and_docs.sh.
Update atk_docs.xml and most .defs files.

* codegen/extradefs/generate_extra_defs_atk.cc: Added get_defs() for new
ATK_TYPEs.
* atk/src/atk_docs.xml:
* atk/src/atk_enums.defs:
* atk/src/atk_methods.defs: Generated by generate_defs_and_docs.sh.
* atk/src/atk_signals.defs: Generated by generate_defs_and_docs.sh. Two lines
modified manually (indicated by comments).
Update Doxyfile.in.

* doc/reference/Doxyfile.in: Update for doxygen 1.8.3. Make it more similar
to glibmm's and mm-common/skeletonmm's Doxyfile.in.
Update .gitignore.

* .gitignore: Add files that are copied to or generated in doc/ and
MSVC_Net2010/atkmm/.
MSVC Solution Files: Use DOS Line Endings

* MSVC_Net2005/atkmm.sln:
* MSVC_Net2008/atkmm.sln:
* MSVC_Net2010/atkmm.sln: Use DOS/Windows line endings as Visual
  Studio expects .sln files to have DOS/Windows line endings in order to
  determine the Visual Studio version to use to open the .sln files.
