Jürgen Spitzmüller ac1977018b ** subfig support **
* src/Buffer.cpp:
* development/FORMAT:
	- bump format to 316.

* src/insets/InsetFloat.{cpp, h}:
	- let nested floats be subfloats
	  NOTE: docbook support is missing.
* src/insets/InsetCaption.{cpp, h}:
	- handle subfigure captions
* src/insets/InsetGraphics.cpp:
* src/insets/InsetGraphicsParams.{cpp, h}:
	- remove old subfigure support

* lib/chkconfig.ltx:
* lib/doc/LaTeXConfig.lyx:
	- check for subfig instead of subfigure.

* lib/lyx2lyx/LyX.py:
* lib/lyx2lyx/lyx_1_6.py:
	- conversion/reversion routines for subfig -> subfloats
	  NOTE: the reversion routine still has bugs.

* src/Counters.{cpp, h}: 
	- add identifiers for subfloats

* src/LaTeXFeatures.{cpp, h}:
	- support for subfig

* src/TextClass.cpp:
	- set up subfloat counter for all custom floats.

* src/frontends/qt4/GuiGraphics.cpp:
* src/frontends/qt4/ui/GrahicsUi.ui:
	- remove subfigure UI.
