[erlang-patches] Fixes messages handling in percept_db

[Ahmed Omar]

Fixes some issues with messages in percept_db

commit 3e8fe28afaf2d78d33dc

Added demonitor to avoid keeping DOWN message in the queue. Also fixed
a wrong spec in do_start/0.


commit 5ba7bf2acdf59cf36dd6:


Fixes message handling in select requests.

percept_db used to send results in an untagged messages, and use a non
selective receive to extract them. When percept is used from the shell
process, this can confuse other messages with the actual result. Added
a tag to the message to be {result, Result}.
