Standardise handling of IED fields (net and ip addresses)
Correct writing to db (seq was assigned a new value which caused duplication in sccpsettings and apparent unsaved data)
Remove inherit button in device and standardise to inherit server settings. Show users what will be set.
Red border if invalid set name
Clean up modal indenting
Define valid chars
Only initialise general section at each save (previously initialised all clearing soft key sets)
Correct error in update mode selection
Save all buttons, rather than to last empty - buttons do not need to be allocated sequentially
Remove on duplicate case - add should always be new as either device is new, or have deleted device data before.
Installer was dropping new 14.3 columns data as these columns did not exist in module.xml schema.
Modify schema to include all columns, including legacy columns, and then move data prior to modifying schema.
Fix Issue #53
Consolidate forms to facilitate maintenance, reduce code, and apply changes to SIP handling introduce for sccp

Do not try to write SEP file if no line defined. Save settings and warn user via toast
Fix feedback to ajax by separately submitting data before return
