v0.1.6

this release enhances usability and reliability

• updated the icon to make it more distinguished
• updated translations (french, russian) and added a czech translation
• make text throughout the UI more standard and easy to understand
• notes are now more reliably saved so that you don't lose your changes
• notes are now restored (mostly) as they were last time you closed the app
• the most recently closed note is now shown when you reopen the app, instead of showing the all notes window

I'd like to take a moment to thank everyone that contributed to sticky notes this far. I
am very grateful for your help and support.
