Provide full list of plugins via "Activate Plugins" list

When creating a new project using the wizard one of the pages allows the user to activate the views plugins. This page should provide a list of all available plugins, together with a description of each. From this page the user will be able to select the plugins they wish to activate in the new project.

This wizard page should be designed in such a way that it can be reused by another wizard to enable/disable plugins in use.
