Stock ACLs prevent com.glide.attachment.max_size property from being checked for non-admin users

The Attachment Size Warning is not shown to non-admin users because the system property com.glide.attachment.max_size is checked incorrectly. The com.glide.attachment.max_size property is checked on the client side using GlideRecord. The stock ACLs prevent the property from being read for non-admin users, giving the impression that the attachment can be uploaded. However, the size limit is still enforced server side so the attachment never uploads and the progress bar is displayed indefinitely.

1. Set com.glide.attachment.max_size to 1.
2. Navigate to /incident.do.
3. Try to load an attachment that is > 1mb.
   The error message is displayed.
4. Impersonate Abel Tutor.
5. Navigate to /incident.do.
6. Try to load an attachment that is > 1mb.
   The error message is not displayed.

Import the attached sys_properties.* ACL, which will extend the read-roles to the field level.

Then, add the public role to com.glide.attachment.max_size.
