For request headers, add a dropdown of common/available header keys

[geigel]

This issue seeks to improve usability of the app. Right now a request header key must be typed in full by the user. Instead, it would be better to either allow the user to begin typing the key for the header and then auto-suggest the completion of a common/available header keys or simply provide a dropdown of common/available header keys.

This functionality exists within an existing desktop Mac program called CocoaRestClient. In that program it offers the ability to type the request header key and also shows a dropdown menu to select. It's a time-saving feature and also reduces errors during input of request header.

I have added menu for choosing some common request header key in the new version 1.3. If they are not enough, tell me what you want.
