Robustness checks: Handling of HTML tags in input

The same checks have been applied to all 9 solutions. Observations are
based on what can be seen in the browser. No internal respresentation
were checked.

Strategy:
- New users robustness and robustness2 were created for the valid and
  invalid HTML tests respectively
- test values were entered as last name or full name
- Status or start pages where checked for representation of names

-------------------------------------------------------------
Results:

Team1:
Valid HTML: appears as verbatim with brackets encoded as entities
Invalid HTML: appears as verbatim with brackets encoded as entities

Team2:
Valid HTML: appears as verbatim with brackets encoded as entities
Invalid HTML: appears as verbatim with brackets encoded as entities

Team3:
Valid HTML: appears as verbatim with brackets encoded as entities
Invalid HTML: appears as verbatim with brackets encoded as entities
Note: Since full name is not shown on status page and also hidden from
search field I had to establish contact (RCD) between to users to see
last name in web interface

Team4:
Note: Name is never shown so no tests can be done

Team5:
Valid HTML: Name appears bold!!!
Invalid HTML: is included verbatim and messes up layout!!!
Note: There is only one field for full name

Team6:
Valid HTML: appears as verbatim with brackets encoded as entities
Invalid HTML: appears as verbatim with brackets encoded as entities
Note: There is only one field for full name

Team7:
Valid HTML: gets passed verbatim and produces bold output!!!
Invalid HTML: is not filtered out and messes up layout!!!
Note: I used firstname here since welcome message only includes
      firstname

Team8:
Valid HTML: gets passed verbatim and we get a bold name!!!
Invalid HTML: gets passed verbatim and messes up layout!!!

Team9:
Valid HTML: appears as verbatim with brackets encoded as entities
Invalid HTML: appears as verbatim with brackets encoded as entities
Note: had to check with four users due to hard-to-use
      interface. Cannot easily check HTML sources due to heavy use of JS
