Pre-Release 3.99.2.0

Please as many users as possible test this version. It will hopefully be the last pre-release before 4.0.0.0. That will be the big move to Python 3.7. This is your last chance to find bugs and get them fixed before that happens.

Remember to check the 3.99.0.0 and 3.99.1.0 changelogs below as well!

Consider this as 'beta2' for the following full '4.0.0.0' release.

• Added Swedish to the translated languages. Thanks to Gurra.
• Will throw an exception, rather than a Segmentation Fault, if run on Linux without DISPLAY properly set.
• Corrects setting of WinSparkle (updates checking) options to be under the new 'EDCD' Registry key.
