This version fixes the two problems of #1:

• If a wrong password is entered during decryption, no (empty) output file is created.
• A single click in the file selection dialogs can no longer enter two directories.

With this version, the mainline fyne module is used instead of my own fork.

spind is in a usable state, but still depends on unreleased changes in fyne. It has been tested on Linux and Windows.

This release only contains the precompiled program for Windows, as this is the first audience I'm trying to reach. Future releases may contain precompiled programs for other platforms like Linux, MacOS and BSDs.
