Control monkey

First commit for direct monkey control which not complete rather just
experimental commit.
Just get ready for direct monkey control and press HOME key using monkey
directly with toast showing just after service created.

Still need more changes to ash and AshFa itself.
 * ash should say good-bye to monkeyrunner completely.
 * AshFa should control connection with monkey safely.
