Allows support for building / running on device via ios-deploy.

It works fine. Can we unify swift-mode:build/debug-ios-simulator and swift-mode:build/debug-ios-device using a special device identifier, such as 00000000-0000-0000-0000-000000000000, representing a real device?

BTW, I have updated master branch for some tweak and checkdoc compliance.

• Please rebase to the master.
• Change :group 'swift to :group 'swift-mode:repl.
• Run checkdoc against swift-mode-repl.el (ignore warnings about word “contains”).
• If user invokes commands with prefix arg, ask scheme regardless of the cache.
