Support the newWindow flag in white-listed app.launchURL JavaScript actions (PR 7794 follow-up)

Browse source 
A simple follow-up to PR 7794, which let's us add support for the `newWindow` parameter; refer to https://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/js_api_reference.pdf#G5.1507380.

The patch also fixes an embarrassing oversight regarding the placement of the case-insensitive flag, and also allows arbitrary white-space at the beginning of JS actions.
