This addresses issue where upon deletion of a form field and all its
entry values, the field record wouldn't be deleted from the `form_field`
table. This links another issue where you can't delete a list if its
been a field before. This is due to the list delete() function that
checks for list field records in the `form_field` table.

i18n v1.10 translation issues

Fixes issue #3620. is_numeric changed in 7.0.0 causing causing the contact form and sometimes login to break. is_string works on any version. The upstream Spyc now uses regex to verify instead of is_numeric, in a way similar to this commit. Waiting on upstream to merge other customizations we've made.

When running osTicket as part of a cluster it might become necessary to
white list local/virtual networks that can bypass some authentication
checks.
