Plugins can not add entries to Global Breadcrumb

Any reason why render-weight needs to be set to 50 for the text to show up? render-weight seems like an unrelated component to displaying a specific entry in the Global breadcrumb?

Hi Ed,

the "breadcrumb" is just another portlet. Since any portlet may add entries to the "breadcrumb", we need this portlet to be rendered after the rest. This is specially important since we have parallel rendering, which means that you might be rendering the breadcrumb in one thread which is executing before another thread is rendering the rest of the portlets.

The render weight controls this:
<!--
The default value of render-weight is 1. If set to a value less than 1, the
portlet is rendered in parallel. If set to a value of 1 or greater, then the
portlet is rendered serially. Portlets with a greater render weight have greater
priority and will be rendered before portlets with a lower render weight.

If the ajaxable value is set to false, then render-weight is always set to 1
if it is set to a value less than 1. This means ajaxable can override
render-weight if ajaxable is set to false.
-->

Breadcrumb portlet has render-weight 1, which means that anything above 1 should be valid. In the core, however, we have standarized this number to 50.

"Backlog" status will be changed "Verified" status.
