Description of the issue:

A variety of links in the manual show up as "Invalid link". When clicking them anyway, the console logs the following error:

[23:59:04] [Client thread/ERROR] [immersiveengineering/]: Unknown anchor start in entry immersiveengineering:refinery (link from immersiveengineering:buzzsaw)

(This was produced specifically with the link labeled "Biodiesel" on page 2 of the Buzzsaw entry).

My current assumption is that the rewrite of the text-splitter took away the default "start" anchors? Explicitely defined ones (such as in workbench.json) seem to still be present and working.

Currently tested on commit 36d7e163
