Disable Delete 7.4

Package is an upgrade from Richard Soetemans Disable Delete for umbraco 4.0.x and 4.5.x

DisableDelete prevents users from deleting document types you don't want them to delete.

The process is simple. Create a new document property with the alias "umbracoDisableDelete" based on true/false datatype and add it to the documenttype. Check the checkbox on all documents that can't be deleted. When a user wants to delete a document that has the  umbracoDisableDelete property set to true, the process will be canceled. 

This will also show an error message for the user to let them know if the document type has a true disable delete property set.

Works well with the package 'Stately' to give an additional icon in the node tree.

This package is compatible with Umbraco 7.4.x+.
