Fix tooltip z-index

[gino0631]

Issue Overview

A p:tooltip is behind pop-up elements.

Current Behaviour

Currently, theme.css sets a fixed value of 932 to a tooltip element:

div.ui-tooltip {
    z-index: 932 !important;
}

As z-index of pop-up elements (p:dialog, p:calendar) is higher than 1000 and is incrementing, this makes p:tooltip invisible (behind the element).

Expected Behaviour

A p:tooltip staying always on top.

How to reproduce

Check the tooltips over Previous and Next buttons of the pop-up calendar:

<p:tooltip/>
<p:calendar ...></p:calendar>

The issue can be fixed by removing z-index declaration from tooltip.less, as it was done in #219 for other components.

Thank you @gino0631, I'll starting to work on a new version that targets PrimeFaces 10 so if you find something else, please create issues.

Just checked with PrimeFaces 8, and was able to reproduce the problem. The screenshot below shows the overridden z-index value:
