Trivial issues. Reporting as one ticket:

• The URL fields should validate that the URL at least starts with xxxx://
  • External CRL Distribution Point (on External CAs)
  • CA Issuer URI
  • Default CRL Distribution Point
  • Default Freshet CRL Distribution Point
  • OCSP service Default URI
  • CA Issuer Default URI

• If no cert file is selected when pressing "Import", you get "An error occurred" instead of "No file selected or upload failed" or similar (we can't distinguish between the two)

• The "Error: Invalid Name Constraint: " error message looks incomplete, there should be something after the colon (to reproduce enter ///xx in Name Constraints Permitted). Or the colon should be removed.
