[B.A.T.M.A.N.] [PATCH 3/3] batman-adv: Convert README to reStructuredText

[Sven Eckelmann <sven@narfation.org>]

The current format of the file is not well defined. The reStructuredText
format (as used by other batman-adv related files) has the benefit that it
is similar easy to read and write. And it allows other tools to parse the
content of the file and convert it in a sensible way to a different file
format.

Multiple git repository web-based management software also can directly
render these files as properly formatted HTML output.

-COMPILE
--------
-
-To compile against your currently installed  kernel, just type:

-if you want to compile against some other kernel, use:

-# make KERNELPATH=/path/to/kernel
-
-if you want to install this module:
-
-# sudo make install
-

-necessary  to  configure  it  using    the   make  options.  Each
