Remove application role

[LJWatson]

When the application role is used, it turns keyboard interaction over to the browser (stripping away all native commands provided by screen readers for navigating and interacting with content. There doesn't seem to be any need to use the application role within this interface, so suggest removing it.

For example here:

<div class="pb-control-oneclickmenu" role="application">

<span class="oneclick-icon icon-ic28-24 oneclick-video" data-icon="sendvideo"></span>

<button class="pb-control-oneclickmenu-title"><span class="text">Video Connection</span><span class="icon-ic14 arrow icon-drop-arrow"></span></button>

<div class="pb-control-oneclickmenu-menu" style="display: none; top: initial;">

<ul class="itemlist">
<li key="sendvideo" class="selected" tabindex="0" aria-selected="true"><span class="text">Video Connection</span><span class="icon-ic14 chose icon-selected"></span></li>
<li key="novideo" class="last" aria-selected="true"><span class="text">No Video</span><span class="icon-ic14 chose icon-selected"></span></li>
</ul>
</div>

Note: where the application role
is used on dialogs, the dialog role would be more appropriate (as noted in #10).
