Using .md extension/Markdown syntax for modules README

Renaming all README files for all top level modules to README.md,
applying no content change at this stage to be able to track history
of the files. These files should be edited to use correct Markdown
syntax later.

+SFX is the "old" framework, used for historical reasons.
+
+An attempt of documentation of this module is located in [git:sfx2/doc].
+
+It contains base classes for document model, view and controller, used
+by "old" applications like sw, sc, sd (while "new" applications
+are based on the "new" UNO based framework in "framework").
+
+The SFX framework is based on dispatching slots identified by integers
+(SlotIDs) to SfxShells, and there is a dedicated IDL compiler (svidl)
+involved that generates C++ slot headers from SDI files in modules' sdi/
+subdirectory.
+
+Documentation about SFX dispatch, SDI etc.:
+https://wiki.openoffice.org/wiki/Framework/Article/Implementation_of_the_Dispatch_API_In_SFX2
+
+Document load/save code is maintained in [git:sfx2/source/doc/docfile.cxx]
+SfxMedium class, which handles all the twisty load and save corner cases.
+
+[git:sfx2/source/appl/sfxhelp.cxx] Start procedure for the online
+help viewer top level window; handling of help URL creation and
+dispatch.
+
+There are also some UNO services here that could really be implemented
+anywhere, e.g. the DocumentProperties or DocumentMetadataAccess.
+
+Notable files:
+sfx2/source/dialog/backingwindow.cxx Startcenter buttons and the corresponding event handler.
