Taxonomy URLs aren't localizable

[jasonvarga]

Bug Description

Taxonomies always use the "current" site when building their URLs.

Also, it always uses the handle in the URL which may not be appropriate for all locales.

cms/src/Taxonomies/Taxonomy.php

Lines 254 to 261 in 06f2341

	public function uri()
	{
	$site = Site::current();
	$prefix = $this->collection() ? $this->collection()->uri($site->handle()) : '/';
	return URL::tidy($prefix.str_replace('_', '-', '/'.$this->handle));
	}
