There are a lot of new rules since the last time I revised the ESLint
rules documentation.
I've updated the main `.eslintrc.yml` to include some newer additions,
plus I added another ESLint configuration file inside `tests`, so we can
add some stricted rules to the production code while relaxing them for
the test suite (due to the fact that Mocha is not very ES6 friendly and
Angular tests require a bit of dark magic to setup).
This is a summary of the most important changes:
- Disallow "magic numbers"
These should now be extracted to constants, which forces us to think of
a good name for them, and thus make the code more self-documenting (I
had to Google up the meaning of some existing magic numbers, so I guess
this will be great for readability purposes).
- Require consistent `return` statements
Some functions relied on JavaScript relaxed casting mechanism to work,
which now have explicit return values. This flag also helped me detect
some promises that were not being returned, and therefore risked not
being caught by the exception handlers in case of errors.
- Disallow redefining function arguments
Immutability makes functions easier to reason about.
- Enforce JavaScript string templates instead of string concatenation
We were heavily mixing boths across the codebase.
There are some extra rules that I tweaked, however most of codebase
changes in this commit are related to the rules mentioned above.

Currently Etcher will allow you to flash an image to the same drive that
contains the image. As a way to protect against that case we introduce
the concept of a "source drive", which means a drive that contains the
source image.
This commit adds the following logic around this new concept:
- Don't auto-select a source drive
- De-select an already selected drive if an image inside it is selected
- Disable the drive in the drive selector modal
- Add a "Source Drive" badge to the drive in the drive selector modal
Fixes: https://github.com/resin-io/etcher/issues/830
Change-Type: minor
Changelog-Entry: Prevent flashing the drive where the source image is located.

Currently the `DriveConstraintsModel` errors when given an `undefined`
drive, or image; this commit changes that behaviour. Comes with tests.

`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`
