Create a 'gettingstarted' plugin and gettingstarted.tests plugin.

This gettingstarted plugin will contain the 
  - 'core content providers' for various types of getting started 
     content.
  - ui bits to make content available to users.

The test plugin will contain regression tests to validate that 
content meets some basic standards. E.g. the codesets they
provide build without error when imported into STS.
