ta_test.html: add some dynamic editable areas for testing
textareas.js: use the mutation_summary library for tracking DOM changes (#71)

The old style DOM event listeners are problematic enough that they are
deprecated. Given that Chrome since version 18 supports DOM Mutation
Observers this makes a lot more sense. Hopefully this will also
prevent the ping-pong with the TrelloScrumm plugin.
README: update with details on the mutation-summary library
textareas.js: we only need one mutation observer.

By cleaning out .added() img tags we probably no longer need all
that hairy code to deal with duplicate IDs.
textareas.js: fix handling of plaintext editable
Merge branch 'master' of github.com:stsquad/emacs_chrome
textareas.js: clean up handleUpdatedElements

Yet another minor cleanup just to make things clearer. Obviously the
handling breaks if the query order is changed so I flag that in the
comments. I've also removed a bunch of needless checking to help speed
things along.
testareas.js: some documentation and un-used var cleanups.

Send textInput event after updating text

After updating the text send a `textInput` event appending a newline to
it. This will cause some sites (at least StackOverflow.com) to update
their preview of the rendered content.  Unfortunately this also causes
an extra newline to be added to the end of the area, but there tends to
be an extra one there anyway.

Send textInput event after updating text
textareas.js: reset content after the extra newline we added

The newline hack is useful for sites that don't notice the HTMLEvents
change event. However we do like to do what the user asks so we reset
back to the content after that insert quickly.

edit-server: add a kludge for edit-server-save restoration

I think this is a bug in Emacs but copy-to-buffer doesn't seem to work
on re-used buffers. So I'll copy the returned text into the kill-ring
for now.
Update NEWS for release
Add some advice before save-buffers-kill-emacs to avoid unnecessary prompt on exit

Also disable the same advice on server stop, to avoid
advice redefinition warnings on server restart.
