Allow multiple values in 'target' array

[aberonni]

Hi,

I'm just creating this because I needed to add two strings to the "target" array and found out it was simpler than I thought.

This is my second pull request ever so please bare with me if I should have done anything else.

I tried launching a test with travis, but it failed due to this infamous bug

Cool, was looking for that feature, too.

Works on my machine! Successfully tested with one, two and zero targets.

Any chance this can be merged into master branch?

Checked out, looks good!
