Added IFTTT to the Providers list

IFTTT is a service that lets you create powerful connections with one simple statement: if this then that. (Learn more at www.ifttt.com/wtf).

IFTTT supports embedding it's recipes through an oembed API, and I have added it to the list of providers, following the format of the other websites in the list.

Finally, made a few spelling changes 'paramater' -> 'parameter'.
