The `--robot` option of the CLI causes the program to output
machine-parseable strings, which can be easily consumed by the GUI to
update progress and other information.
The problem is that if the CLI fails to parse its command line arguments
when being called from the GUI for whatever reason, the `.fail()` Yargs
handler will be called, which doesn't output error information in the
usual "robot" format, causing the GUI to not understand the error
message.
Since the `.fail()` Yargs handler doesn't have access to the passed
options, we moved the "robot" functionality to an environment variable,
which we can easily check from there.
As a bonus, this PR refactors the whole robot logic into
`lib/shared/robot.js` and adds unit tests to it.

We've recently PRed a commit that handles multiple IPC messages being
triggered at the same time, confusing `JSON.parse()`. As a solution to
such problem, we are splitting the CLI output on new lines, based on the
assumption that each line represents a different object, however we
didn't consider that in the case of errors, we include an `stacktrace`
property which usually includes new line characters, causing such
information to be completely garbled and cause `JSON.parse()` once again
to get confused.
As a solution, we only split by new lines that are not surrounded by
quotes (since they represent a JSON property).

`SelectionStateModel`'s methods `isSystemDrive` and `isDriveLocked`
don't depend on application state. They have been extracted in a different
AngularJS service: `DriveConstraintsModel`. The new service's actual
implementation is in `lib/src`, in order to be reused by the CLI.
Miscellaneous changes:
- Rename `lib/src` to `lib/shared`
- Refactor `drive-constraints` to throw when image is undefined
The default behaviour was to pretend that we're all good if the if
the image is not specified. We're not using this "feature", and
it can be dangerous if we forget to pass in the image.
- Make `isSystemDrive` return `false` if `system` property is undefined
- Use `drive-constraints` in `store.js`
