Vidrio for Mac v1.18: two more translations and a bug-fix

30 Apr 2020

More translations!:

• Rizo contributed a Ukrainian translation! Дякую тобі! 🙏
• Torkel Spindler contributed a Swedish translation! Tack! 🍻

We also fixed an obscure bug: under certain unlikely conditions (such as having the local time set incorrectly), Vidrio would crash due to modifying the UI on a non-main thread. It now sticks to the main thread.
