commit 85fd9ee4801fe6a2f4f4dc745a6e635ac186bb42
Author: Michael James Gratton <mike vee net>
Date: Thu Oct 6 23:09:21 2016 +1100
Begin the WebKit2 port in earnest.
Replace StylishWebView with ClientWebView, to act as a common base class
for the composer, conversation and other uses of web views.
Introduce a ComposerWebView that replaces WebviewEditFixer and extends
ClientWebView, and adds (dummy for now) methods for ComposerWidget to
call. Simiarly, make ConversationWebView extend ClientWebView, add dummy
calls to support the conversation viewer classes. Move common code from
both into ClientWebView.
Add a web-process library, unused other than for compile-time checking,
and move all client functions and methods involving DOM objects into util
classes there.
