Title: MODx.tree.PackageBrowserTree reload on provider change

When changing the provider, the tree is now "refreshed".

Additionally, if any error message happen, it is displayed in a MODx.msg.alert with a "callback" reloading.
This is mainly to prevent having the error message in the tree element (preventing any further "refresh").
