tc server instance creation options page problems

We added a page to the wizard for creating a new tc server instances to allow people to configure the available options for each template. This page seem to have a few issues:

• some options are duplicated on the wizard page. I guess this is because of some special configuration in the properties file of the template, but we should avoid this confusion.

• the wizard complains about missing values for some templates (bio-ssl for example), whereas the script on the command line creates the templates without any additional parameters.
