documentation/Makefile: new 'edison' variable for YP dev manual.

I discovered that the figures used in this manual differ depending
on the branch.  There are two figures that are different.  Thus,
the TARFILES variable in the makefile needed to be conditionalized.
If it is not, then the process that makes the tarball throws errors
because it cannot find the two figures from the other branch.

To fix this I introduced the 'BRANCH' variable.  It is to be used
only when you make or publish the YP Development Manual.  And, you
only use it to specify 'edison'.  If you are building from the 'master'
branch you don't need to use it.

Comments in the file have been updated to explain usage.

 # To build the HTML and PDF versions of the manual you must invoke the Makefile

 # Examples:
 #
 #     make DOC=bsp-guide
 #     make DOC=yocto-project-qs
 #     make pdf DOC=poky-ref-manual
+#     make DOC=dev-manual BRANCH=edison

+# The first example publishes the 1.2 version of both the PDF and HTML versions of 
+# the BSP Guide.  The second example publishes the 1.2 version of both the PDF and 
+# HTML versions of the ADT Manual. The third example publishes the PDF and HTML
+# 'edison' versions of the YP Development Manual.  Finally, the last example publishes
