This splits up the definitions from the buildtool into a seperated file
called Elementary_Options.h.
Reason for that is, that every single time when someone adds or changes
something in Elementary.h.in you need to rerun configure, to get the new
up to date Elementary.h file. With this commit you have a static none
generated Elementary.h file and the Elementary_Options.h file, which
will be regenerated when platform things are changing.
The version of elementary is now defined as the version of efl, since
they are always the same. So we dont need to generate a seperated
version field.
