[test_server] Fix erl2html2.erl to handle badly indented files

Line numbering of erlang files that were not correctly indented could
be wrong after coverting to html with erl2html2:convert/[2,3]. This has
been corrected.

This commit also fixes the following:

* There are now link targets for each line and not only for each 10th
  line - meaning that links from test logs are now to the exact line,
  and not to the last number for which N rem 10 == 0.
* there will only be one link target per function, i.e. the faulty
  link targets for function clauses are removed.
* link targets for function now includes the arity (e.g. func/1 has a
  link target "func-1")

And some tests are added.
