Remove unused image assets: icon.png and screenshot-gui-for-ffmpeg.png. Moved to assets folder.

Extended `FFplayContract` with `GetVersion` to fetch FFplay version. Implemented version extraction in `utilities` and `ffplay` to support version retrieval functionality.

-Простенький интерфейс к программе ffmpeg.
+<p>Простенький интерфейс для консольной утилиты FFmpeg. Но я <strong>не являюсь</strong> автором самой утилиты <strong>FFmpeg</strong>.</p>
+<p><strong>FFmpeg</strong> — торговая марка <strong><a href="https://bellard.org/" target="_blank">Fabrice Bellard</a></strong>, создателя проекта <strong><a href="https://ffmpeg.org/about.html" target="_blank">FFmpeg</a></strong>.</p>

+
+## Установка через fyne:
+1. go install fyne.io/fyne/v2/cmd/fyne@latest
+2. fyne get git.kor-elf.net/kor-elf/gui-for-ffmpeg
+
+## Скомпилировать через Makefile:
+1. git clone https://git.kor-elf.net/kor-elf/gui-for-ffmpeg.git
+2. Переходим в папку проекта и там переходим в папку src: **cd gui-for-ffmpeg**
+3. Ознакамливаемся, что нужно ещё установить для Вашей ОС для простого запуска (через go run) тут: https://docs.fyne.io/started/
+4. go install github.com/fyne-io/fyne-cross@latest
+   * У Вас так же должен быть установлен docker
+   * О fyne-cross можно по подробней почитать тут: https://github.com/fyne-io/fyne-cross
+5. * make build-for-linux_amd64
+   * make build-for-windows_amd64
+   * Или просто **make build** 
+6. Создаться папка с архивом в **fyne-cross/releases**
+
+## Скомпилировать через исходники:
+1. git clone https://git.kor-elf.net/kor-elf/gui-for-ffmpeg.git
+2. Переходим в папку проекта и там переходим в папку src: **cd gui-for-ffmpeg**
+3. Ознакамливаемся, что нужно ещё установить для Вашей ОС для простого запуска (через go run) тут: https://docs.fyne.io/started/
+4. *(не обязательный шаг)* Просто запустить можно так: **go run main.go**
+5. go install github.com/fyne-io/fyne-cross@latest
+   * У Вас так же должен быть установлен docker
+   * О fyne-cross можно по подробней почитать тут: https://github.com/fyne-io/fyne-cross
+6. * fyne-cross windows
+   * fyne-cross linux
+7. Создаться папка **fyne-cross/dist** и там будет созданна папка с тем названием под которую Вы компилировали приложения (linux-amd64 или windows-amd64).
+8. В папке **fyne-cross/dist/linux-amd64** или **fyne-cross/dist/windows-amd64** будут архивы, которые надо распаковать и пользоваться программой.
