Screen To Gif 2.18

What's new in this version:

New:
- Added support for presets/profiles for FFmpeg video encoding feature, separated by file type
- Keystrokes: The app will display "Ctrl" instead of displaying "Control"
- Updated the Korean translation

Bug fixes:
- The process that checks if there's already a file with the same name was changed. Now it should be smoother
- In Options > About, the Gitter link was opening other website by mistake
- The task that alters the delay of frames was not working
- The transition "Fade to color" was ending with a frame not 100% of the selected color
