Use of device UUIDs
upgraded express version
closes #86
added `tishadow close` command
closes #87 - added the `@` watch operator to cli

You can now use commands like the following:
`tishadow @ run -l nl -u -r secret`
or
`tishadow @ spec -u -r secret`

The command following the `@` character will be
executed on file changes in the `Resources` or 
`spec` directory.

Think of the `@` like a loop character.
