Added: Changed idn function to support multi-line fields (like mail forward)

- need to have the pecl idn and intl modules installed
  or
- have the idna_convert class in the classes/idn/ path

Fixed/Implemented: replaced intval() by $app->functions->intval() in all interface functions due to big number problem in intval()

Added: Form fields are disabled if a client is not allowed to edit a domains main settings

- Implemented: FS#1935 - Add minimum allowed seconds Value for DNS zone records

Fixed: FS#2109 - Email address validation via API method(s) is inadequate (and results in false-negatives)

- Added a new IP validator to the tform library which validates IPv4 and IPv6 addresses.

I've changed the id HTML attributes of the check boxes. You can still group post requests on name attributes while using the id to keep the items unique in the DOM tree. i saw some commented code already being there but wasn't functioning, so i rewrote the original lines.
This only goes for type: CHECKBOXARRAY and RADIO

- Fixed {RECORDID} placeholder in SQL datasource strings.

Added global functions library which conatins a mail functin that supports attachments and a array_merge function that merges arrays that conatain numeric keys and strings correctly.
