    Attachment: MR2751.patch

- Gets rid of a bunch of left over files (either directly or by creating them under an app/container

- Not directly related to the Jira, but some changes to the Application statemachine for ignorable
transitions, and tests for Application.

> This ticket is about app-only files which should be cleaned after app-finish.
> I see these undeleted after app-finish:
> /tmp/nm-local-dir/0/nmPrivate/application_1305091029545_0001/*
> /tmp/nm-local-dir/0/nmPrivate/container_1305019205843_0001_000002/*
> /tmp/nm-local-dir/0/usercache/nobody/appcache/application_1305091029545_0001/*
> We should check for other left-over files too, if any.
