Core: complemented Gst module
Test: added tests for Gst module
Gst::Allocator: wrapped GstAllocator struct.

	* .gitignore: added allocator generated files, test *.log
	and *.trs files to ignore list
	* gstreamer/gstreamermm.h: add allocator header to core includes
	* gstreamer/src/allocator.ccg:
	* gstreamer/src/allocator.hg: implemented GstAllocator wrapper
	* gstreamer/src/filelist.am:
	* gstreamer/src/gst_vfuncs.defs: added allocator's virtual
	functions definitions
	* tests/Makefile.am:
	* tests/test-allocator.cc: added a few tests for Allocator wrapper
	* tools/m4/convert_gst.m4: added conversions definitions between
	AllocationParams and GstAllocationParams, Memory and GstMemory
Gst::AtomicQueue: wrapped GstAtomicQueue module.

Gst::AtomicQueue is template class. It helps with control queue types.
For exactly the same behavior as GstAtomicQueue, gpointer as template
type might be used.

	* .gitignore: added atomicqueue test executable file to
	ignore list
	* gstreamer/gstreamermm.h: atomicqueue header to a core includes
	* gstreamer/gstreamermm/atomicqueue.h: atomicqueue wrapper. This
	file isn't autogenerated, because Gst::AtomicQueue is template
	class.
	* gstreamer/gstreamermm/filelist.am: atomicqueue header as an
	extra header.
	* tests/Makefile.am:
	* tests/test-automaticqueue.cc: added a few tests for
	Gst::AtomicQueue class.
Gst::Bin: updated GstBin wrapper.

	  * gstreamer/src/bin.hg: Updated handwritted comments. Wrapped
	  GstBinFlags enum and children_cookie member. Removed deprecated
	  gst_bin_find_unconnected_pad ignore macro.
doap: updated doap and other project info files.

      * AUTHORS: list all gstreamermm contributors.
      * MAINTAINERS: removed file, doap file exists instead of this file.
      See here: https://wiki.gnome.org/Git/FAQ
      * gstreamermm.doap: added language info, updated category and
      link to bugzilla page.
Gst::Bin: added more tests to GstBin wrapper.

	* .gitignore: added test-bin file to ignored list
	* tests/Makefile.am: previously Bin test file wasn't added to a
	makefile. I fixed it in this commit.
	* tests/test-bin.cc: renamed existing tests, added tests for most
	of functions, virtual methods, signals.
