[Dillo-dev] [patch]: html.cc: remove MSG_HTML and rename Html_msg() to DilloHtml::message()

Self-explanatory, I hope. This is a useful bit of yak-shaving to prepare for more refactoring of form handling code. The reasons for removing MSG_HTML are: * It doesn't belong in msg.h since it can only work when used in http.cc . * It's a UI function not a debugging function like the other MSG_* so it's misleading for it to look similar to the MSG_* macros. * Using it has no advantage over simply calling the function that it wraps. * It's fragile because it requires html to be in scope and have the right value.
