Hide DNSSEC from Wizard if DNS-Mirrors are available (prevents broken DNSSEC-Implementaion on Multiserver-Setups)

Hide DNSSEC from SOA if DNS-Mirrors are available (prevents broken DNSSEC-Implementaion on Multiserver-Setups)

Forgot one template for tooltips as mentioned in: ispconfig/ispconfig3#3995

Fixed issue #3955 DNS module: Limit for maximum zones can be circumvented with "import zone file" function.
Removed TODO string in error template.

This Checkbox can be enabled or disabled by template.

Further I fixed an inconsistent design (HTML) which was introduced by @tbrehm yesterday I tink. (DKIM-Checkbox)

Added sone lines to rmeoting api description file for dns (I hope thats correct...)

This one also sets type SPF as well as two records within DNS as of RFC4408
Hop that's okay?

This is a considered as stable stable release. (tested the workflow successfully)
Note: I am not perfect at RegEx I know the RegEx for LOC- and DS-Records is actually not checking. The DS-Regex is definitely valid (tested on regexpal).
Along with my dns-status modification this should not be a problem at all.

And found a small bug (privkeys were not deleted on zone deletion) which is now fixed
Testing successful. Doing last test then if everything goes well this will be the new merge request
