Various bugfixes and changes
1: Script had AAAA hardcoded, this would've changed all records to AAAA.
2: Script was not saving the DNS Records ids, only their names this would've made it impossible to actually edit the DNS Record
3: Lowered the amount of printing going on, removed irrelevant information such as zoneid from the print statements, also removed most printing during the update phase
