Z-Wave: Node Deletion & Add Controller IsFailedNode

A Z-Wave node can only be deleted if its present in the controllers
"Failed List" resident in its own NVRAM.
Added the Z-Wave IsFailedNode Message Class.
Added new Failed status if the controller has it flagged as failed in
its own database.
This then allows a node to be deleted.
Visibility of the "Delete Node" button uses this new logic.
Z-Wave: Node Deletion - improve FailedNode logic

Remove unnecessary call to delete node xml - already done on success
event at controller level.
Allow a FAILED node to be set to alive again if packets are received
from it.
Heal process of failed nodes handled correctly.
Z-Wave: Failed Node - Add "Failed" boolean status

Added "Failed" status to config
Consolidated status info.
Removed the 'failed' status and changed the 'node stage' to provide the enum so the client side can see what state the device is in.
Move requestIsFailedNode to NetworkMonitor

To ensure always gets called when a node is marked as dead during
runtime.
Thanks to Chris for the advice!

Update Fibaro devices with value 255 used in a list.
ZWave defines configuration values as signed numbers, however Fibaro lists some numbers as signed. This can be resolved for values that are typed in, however for values in lists, this needs to be treated as signed, otherwise the system will ignore these values.

Fritzbox Binding log message #881
Add support for Everspring AD131

This is a plug-in dimmer module. It seems to be
identical to the AN142.
Add null checks to ZWaveDbProductFile

Both everspring/ad131.xml and everspring/an142.xml (and many others)
have a missing <Configuration> section. This causes a NPE while parsing
the database. I’ve fixed this in ZWaveDbProductFile#getConfiguration()
by returning an empty list instead. Same fix applies to
ZWaveDbProductFile#getAssociations()
