remote-viewer: add a default extension to screenshot filenames

Browse Source 
When doing a screenshot, if the user provides a filename without a file
extension, an error occurs because the image format could not be determined.
This patch adds a .png extension to such filenames, so that there is a default
file format for screenshots.
