This pull fixes a case where libraries that a sketch uses indirectly (other libraries is uses require them) need to be included directly in order to compile.
It is necessary to #include a library's file in your sketch in order for the IDE to add that library's path to the compiler command line. This patch searches the files that are included as well, adding dependent libraries to the search path. This removes then need to directly #include indirectly used libraries.
It takes into account also Matthijs suggestion:
Moreover:
BTW, I'm still not fully convinced about this patch, more tests welcome.
