WhatsApp: Support for WhatsApp Web by updating url

[NoNamePro0]

Short: Make the WhatsApp-Links compatible with WhatsApp Web

By using https://api.whatsapp.com/send?text=A Text instead of whatsapp://send?text=A Text

Pull Request #366 makes the same, but using wa.me which is just a redirect to api.whatsapp.com. So for the performance, this pull request with this link is better.

This pull request will fix #352

Overview Links

Mobile Only

• whatsapp://send?text=A Text

Web and Mobile

• https://wa.me/send?text=A Text (Redirect to api.whatsapp.com)
• https://api.whatsapp.com/send?text=A Text

Seems to be correct according to https://github.com/bradvin/social-share-urls#whatsapp.

@compeak I've tested this PR with success with WhatsApp on mobile (iPhone) and also with the WhatsApp Desktop App for Windows 10, so I think it can be merged.

@NoNamePro0: I think it would be a good idea to set the "popup" parameter to "true" (popup: true,). Otherwise the WhatsApp link opens in the same tab (on desktop browsers; tested with Google Chrome), which is not the ususal Shariff behavior.
