Title: Fixed so that gulp runs images more than once

I noticed gulp only running the 'images' task once, so I removed `once: true` from that task in `gulpfile.js`.

This seems to show output whenever you add an image to the `apps/images/` directory, but I'm not sure if the output is correct, so I'm not sure if you want to merge it yet:
```

[19:29:33] gulp-size: 'images' total 22.57 MB

```

Without this change I only get the output:

```
[19:29:30] Starting 'images'...
```
and no other output if I add additional pictures.
