Galaxy versions: Make it clear what EDMC's support is for Live/Legacy

* Inara is Live only.
* We send `gameversion` to EDDN and EDSM, the code listening to the
  messages decides what to do.

+## Supported Game Versions
+In the game's [Odyssey Update 14 the game galaxy was split in two](https://www.elitedangerous.com/news/elite-dangerous-update-14-and-beyond-live-and-legacy-modes):
+
+- 'Legacy' for consoles and anyone playing using the 3.8 Horizons client.
+- 'Live' for anyone playing using the 4.0 client (Horizons or Odyssey).
+
+Elite Dangerous Market Connector *does* support both, but starting with version
+5.6.0 the focus will be on supporting 'Live' galaxy players.  A lack of 
+testing against the 'Legacy' galaxy might lead to bugs only triggered by 
+such play.  Bug reports for such are still welcome, but will have a lower
+priority than anything that (also) affects 'Live'.
+
+This application sends the `gameversion` as stated by the game client in all
+EDDN messages, and also in each batch of messages to EDSM's API.  The sites
+the other end choose to accept or drop any such data.
+
+In addition to this the major third-party websites and tools are mostly
+choosing to only support the 'Live' galaxy.  In particular:
+
+- Those listening to the EDDN data stream will tend to only pay attention to 
+  'Live' galaxy data.  So don't be surprised if, e.g. a station's market,
+  does not update if you are playing 'Legacy'.  Also, the data on such 
+  third-party sites may will not match that seen in 'Legacy'.
+- Inara [has chosen](https://inara.cz/elite/board-thread/7049/463292/#463292)
+  to only support 'Live' data on its API.  Thus you can no longer track any
+  'Legacy' commander using it.  The Inara plugin code in Elite Dangerous 
+  Market Connector will not even attempt to track 'Legacy' data, never mind
+  send it to Inara.
+
+  If you are only playing in the 'Legacy' galaxy you should just disable the
+  'Inara' plugin's sending of data, else you'll get a warning every time an
+  attempt is made to send such to Inara.

+galaxy is supported by Inara**.  Thus, if you are playing only in the 'Legacy'
