Currently plugin owners can request verifications for all NetBeans versions (6.0, 6.1 and 6.5). Theoretically, after
couple of years the team of Verifiers would need to have installed many NetBeans versions although majority of people
use don't use the old releases. Thus I am proposing to support only limited number of released NetBeans versions (e.g.
2) and don't offer the rest for verifications. The UI for managing NetBeans versions could look like this:

New version: [      ] [Add]

Version       Verifiable           Action
============================================
  6.0            [ ]              [Delete]
  6.1            [x]              [Delete]
  6.5            [x]              [Delete]

There would be module catalogs for all versions but the ones for not verifiable versions would only be static.
