Change Essentials plugin name 'Content Blocks' in 'Content Blocks plugin'

If an Essentials plugin creates new template composer components, it is named 'component' in the Essentials UI. If a plugin also creates new document types and more, it is referred to as 'support', which is a wider naming. If it matches a Hippo Forge plugin, it is called 'plugin'. Currently, the UI contains 'Content Blocks', but it should be changed to 'Content Blocks plugin', as this is from Hippo Forge.
