Reco 2.2.0 Released

• Getting/setting window positions gets more efficient; Now it uses fewer keys and prevents position changes from being spammed
• Fix the app does not resume the pause icon when you cancel recording while pausing it
• Fix the app shows the successful mark even if a recording is not saved correctly
• The app now saves and restores values typed into the spin buttons. This is because of using GLib.Settings binding when possible
• Good news for contributors who would like to translate the app! The translation guideline came back. Check it out here
• As always, the source code got refined. I removed some stale, unnecessary, or redundant properties and comments. This time, in addition, codes that handle recording was separated from ones that describe UI, which should improve the readability of codes
