sendkeys: Merge in latest upstream commit that mostly works

Browse source 
5c034c108c
seems to be the newest upstream commit that still works. After that,
`{selectall}` doesn't seem to work. Starting with v3.0, sendkeys sends
input events instead of keypress events, which `ace2_inner.js` doesn't
listen for.
