Submitting links to queue (ideas):
- Re-set crawled entries (crawler)
- Making URLs from realurl page-cache table? (DS req?)
- Frontend link generator can also store a URL in the queue!
	- Only cachable URLs
		- Either standard params like MP / id / type or cHashed params
		- Solution:
			- A hook in linkData() or the like makes it possible for "crawler" to insert a URL in a new table of "visited URLs" which can be (regularily) transferred to the crawler queue (DS req. for P&S section!!)
- When indexed search would otherwise have indexed a page, simply add it to queue.
