Tiny fix to code formatting
Removes the indication that Resources is a Modelica Package

The point of the Resources directory is that one does
put any NON-Modelica material in here. So Resources should
most certainly not be marked as a Modelica package.
Removes an unnecessary "tick".
Adds missing header indicator
Adds missing colon to activate "todo" again.

Syntax fixes
Fixes #181 by making TODO list appear ONLY if condition is true

We can simply reuse the `todo_include_todos` condition.
However there is a little quirk to it when trying to hide
the TODO entry from the TOC. The conditional entry can only
be of lower level than the preceeding one. So that's why I
changed the level and put it under the "Indices and tables"
section.
