Two corrections for 1.1.1

### Addresses two issues.
1. Correctly handles sslVerify for certificates user explicitly told OS to trust.
2. Setting certain urls in jss url text field would freeze the OS, this is more robust way to test the url as well as it now pipes back redirected urls to the UI.  This may address the new jamfcloud naming scheme that uses a FQDN instead of `https://jss.jamfcloud.com/[instance]` causing issues where the api is not accessible from the latter.
