Test suite for pictures and no-pictures modes

[pehrlich]

Seems like there would be a good way of going about this by:

• making an html testing page (sort of like testbed.hmtl)
• Adding on appropriate markup, such as this [role=log] element:

<div class="Z8Dgfe" role="log">
    <div id=":4t" class="kf">
        <div class="kj"><img id=":0_3" name=":0"
                             src="/mail/c/u/0/photos/public/AIbEiAIAAABDCI343MDK09r2ASILdmNhcmRfcGhvdG8qKDI2NGMyMzkyMGJmNTdjZjYyZWIzYzUxNjAzMTk0MTVjOGU0YmZkNWMwAZf5StKzmrfhbOILtHRG54clAMhn?sz=32"
                             class="kh aeb" jid="[email protected]"></div>
        <div chat-dir="t" class="aec">
            <div class="kk">
                <div class="kn" title="[email protected]">Peter</div>
            </div>
            <div id=":5n" dir="ltr" class="kl">wefqwef</div>
            <div id=":5o" dir="ltr" class="kl">qwefqwe</div>
        </div>
        <div chat-dir="" class="kq" role="chatMessage">
            <div class="aef" title="Sent at 12:18 PM on Wednesday">12:18 PM</div>

        </div>
        <div chat-dir="" class="kq" role="chatMessage">

• writing tests for various easy things, such as HUD being added to the right places, and click events being responded to
• finally, add Travis-CI to the repo, for automated testing
