sort exported views by view name so exported views can be compared with diff, patched, and versioned

The current sort method of the Bulk Export module appears to be that the module exports all views from the database and then all views that are set up in the hook_views_default_views.

This makes it difficult to compare exported views. Also version control is not leveraged effectively to store just the actual differences between versions, because version 100's view is down deep in the package of views and version 101's modified view is at the top because it's being exported from the database.

This patch sorts all views alphabetically before they're exported. This makes comparisons easier and version control a little happier.
