Feature/projects (#18)

* add up to 5 attachments

* multiclause function event handler

* fix incorrect Cog calls

* add default param as "all" so we can start differentiating the types of identifications in the future - projects / diseases

* abstract message sending

* overwrite global application commands

* pass message from projects to message sending and id functions
