Fixed undesired submit action

[andaviaco]

If you use ui-select inside a form, the form gets submitted when you click the 'caret' button, by adding a type in the button it prevents this behavior :3.
tested in Chrome v.38.0.2125.122 using AngularJS v.1.2.27

@brianfeister not really, the second button doesnt have a type:

<button class="ui-select-clear" ng-if="$select.allowClear && !$select.isEmpty()" ng-click="$select.select(undefined)">
    <i class="glyphicon glyphicon-remove"></i>
</button>

Fix released in v0.9.6
