Add support for paste as plaintext
Requires new WebKitGTK APIs:

Fixes #415 (closed)
WIP until after WebKitGTK 2.29.2 is released... assuming that will contain my new editing command. P.S. it's testable with 2.29.1 if you simply replace WEBKIT_EDITING_COMMAND_PASTE_AS_PLAIN_TEXT with "PasteAsPlainText".
