Pre-Release 3.99.5.0

Consider this as 'rc2' for the following full '4.0.0.0' release.

• Fix for using EDDB as System provider. It was picking up a wrong
  SystemAddress from the Frontier CAPI (it's a bug their end). Now the CAPI
  will only be used for this when we don't already have a value, otherwise
  we always get the new value from Journals anyway.
• Tweak to Inara plugin so it will send updates via the Inara API more
  frequently. Will now send an update, no more often than about once a
  minute, if your cargo changes at all. This still won't update if you dock
  and quickly buy or sell some cargo, but it's better than it was before.
  You can nudge it by waiting a minute then re-opening the Commodities screen,
  or indeed performing any other action the logs a new Journal event.
