[0.14.5] [Twinsen] Error when loading 0.10 map in Map Editor

[Kevin94]

When loading an old scenario in the Map Editor with a map-format the current version can no longer read, Factorio closes immediatly.

The Map Editor should handle this like the base game too, showing a nice error popup and not closing the game.

I dont really know where right now but somewhere Factorio staff wrote that you need to save the map in 0.12 so you can use it for later versions...

I know that. The point of this Bug Report is, that Factorio makes a Crash To Desktop, when I try to open such an old Scenario in the MapEditor.

(You could argue, that it's only a crash when there were an unexpected error that wasn't handled properly, like a Segfault. But in my opinion, from the position of a user, any program exit without a proper error dialog is a crash. Even when there is a nice explanation in some (hidden) log file.)

Fixed in Version: 0.14.6

Now it shows a dialog with the error instead of crashing.
Also did some other minor improvements to the error messages and interaction when loading normal saves to make errors clearer.
