When exporting a solution with a plugin package component, the pluginpackageid isn't exported. This cause an issue where importing the solution will generate an unique pluginpackageid per environment.

XrmToolkit uses 'PluginAssemblyPackageId' to match plugin packages based on pluginpackageid. This can cause an issue when using the same plugin package across multiple environments.

Ideally we would like XrmToolkit to match plugin package based on the name rather then the pluginpackageid.
