including global plugin imgAreaSelect breaks deamdify-ed modules which requires it

If a module contains the line:

```
require('...path.../imgareaselect/jquery.imgareaselect.js');
```

which is this file:
https://github.com/odyniec/imgareaselect/blob/new/jquery.imgareaselect.js

Then the transformed bundle will have the module's code messed up. Comments and new lines are removed, and even some brackets are removed.

For example:

```
config.screenshotareaselect.setOptions({
x1: x - (width / 2),
x2: x + (width / 2),
y1: y - (height / 2),
y2: y + (height / 2),
```

becames

```
config.screenshotareaselect.setOptions({
x1: x - width / 2,
x2: x + width / 2,
y1: y - height / 2,
y2: y + height / 2,
```

Reproduce the transformation with a module requiring jquery.imgareaselect.js, then compare the transformed bundle with the source example in the report. Trace how that dependency is parsed and transformed; done means the module's comments, newlines, brackets, and arithmetic grouping are preserved in the generated bundle.
