[TASK] Restructure typolink tag generation

Information for creating the target and the class information etc. is
spread through the main function. Putting everything in one place and
using an array for building the <a> tag seems to be more appropriate.

The functionality for building the tag could now be moved in to a
separate function in a next step. Alternative would be to move the
resolving of the "target" field into a separate method.
