* Fixes#1655
Further field name references were found in `consoleport.html`. These have now been removed, so we rely on proper a proper `__str__` implementation of both `ConsolePort` and `ConsoleServerPort`.
* Fixes#1655: Removed explicit field references
Cleaned up all (notable) .name references, and removed them so __str__ can do the lifting. Did not remove the references where it was explicitly referenced to .name (eg. in details). Extended the Secret model to also include the name in __str__, since that was weirdly absent.
* Adapted PR to comply with comments
Re-introduced certain references to make sure explicit references are still used where needed.
* Fix#235: Enable global vlan
Decouple site/vlan, make site optional for vlan/vlangroup
Change html generation code to check site existence before
dereference
Create site search function, if site is None for a VLAN, view it as
global VLAN
