Make application version and study name visible

[LDSamson]

• Make application version visible
  • can be obtained using golem::get_golem_version().
• Make study name visible
  • Study name should be added to the config file.
• Make new/updated markers more consistent (remove asterisks, show only in bold)
• Replace the term 'patient' for 'subject' or similar (more general term)

@LDSamson I'm curious about what you envision with the usage of golem::get_golem_version(). Is there a reason to use this over golem::pkg_version()? The first option reads from the configuration file, so we would be setting that value. The second option reads from the DESCRIPTION file.

Reading from the description file is fine and maybe even better.
