Update spec to reflect addition of maplike<> to WebIDL

[qdot]

The blink implementation of WebMIDI is now using maplike<> (https://code.google.com/p/chromium/issues/detail?id=432683), and the firefox implementation (https://bugzilla.mozilla.org/show_bug.cgi?id=836897) will most likely use maplike<> once is in place (https://bugzilla.mozilla.org/show_bug.cgi?id=1123516). The spec should reflect this so we don't have discrepancies.

The problem is that ReSpec doesn't support maplike right now. w3c/respec#361

[yutakahirano]

I'm trying to fix that.

[toyoshim]

shall we close this now, or keep it opened until ReSpec support maplike?

[yutakahirano]

ReSpec released a new version containing maplike (it was faster than I expected) and I would like to drop the workaround soon.

[toyoshim]

great!

Yutaka-san, reference? I can't find a new release of ReSpec that supports maplike.

Done.
