Consistent problem templates:
- New line after each tag (not for texts in foils)
- One empty row after each end tag and before new start tag for second level tags
- No indentation for second level tags, e.g. <script>
- Four white spaces as indentation for each further sub level
    Exceptions:
        -Content (mostly text) in separate line(s): no indentation
        - Concept groups: same indentation as foilgroup
          (allows to insert code from problems without concept groups without changing the indentation and vice versa)
- No new line at end of template
- Removed new lines from within the middle of default texts
- Added one blank each after "<m>$" and before "$</m>" to ensure no misinterpretation neither by human nor by machine (e.g. "<m>$x" is not "<m>$ $x")
- Replaced deprecated font tag in <instructorcomment> by CSS
- Removed dos line endings
- dos2unix conversion
