ProjectExplorer: Add option to stop applications from the same build directory

Creator can stop running applications when a build starts. This prevents isssues
on windows where the running application locks files in the build directory, which
in turn will make the build fail.

In addition to the current options to kill all applications or just those from the
current project, add a new option to kill all applications of the current project
that live in the same build directory.
