Update to version 2.0. Port to GTK4.

- Added `resources.c` and `resources.h` to the `.gitignore` file.
- Modified the `execute_command` function to use `g_spawn_command_line_async` for asynchronous command execution.
- Updated the `show_confirmation_dialog` function to display a GTK dialog with a warning icon and improved layout.
- Added a margin to the buttons in the `create_button` function for better spacing.
- Improved error handling for loading the window icon in the `activate` function.
- Updated README.md with more information about manually compiling ssdd

+# ssdd: Simple Shutdown Dialog for Openbox
 
-A simple Shutdown Dialog for Openbox written in C using GTK 
+A simple Shutdown Dialog for Openbox written in C using GTK 4
 
 ![Project Screenshot](ssdd.png)
 
-## Why?
+![Settings screenshot](ssdd-settings.png)
 
-I just bought a new laptop and on my workstation I was using [ssd from Sawfish](https://github.com/SawfishWM/ssd) which I loved. I didn't want to go through all the steps of installing the necessary libraries and dependencies to get it to work, so I decided to create my own.
+![Settings screenshot](ssdd-about.png)
 
-## Dependencies and compilation
+**Simple Shutdown Dialog (ssdd)** is a simple yet stylish shutdown dialog for Openbox, crafted in C using GTK 4.
 
-This app requires GTK+ 3.0 development libraries and gcc or clang.
+## Why ssdd?
 
-I am using this command to compile the program:
+As a long-time Openbox enthusiast, I've always found the default exit dialog a bit lackluster. Modern systems deserve a more refined shutdown experience. While there are other options out there, I figured one more wouldn't hurt, right?
+
+Inspired by the elegant `ssd` from Sawfish, I decided to create my own tailored solution for Openbox.  This way, you can avoid the hassle of installing extra dependencies and enjoy a sleek shutdown dialog that complements your Openbox setup.
+
+## Features
+
+- **Clean and Intuitive Interface:** ssdd presents clear options for Logout, Reboot, Shutdown, Switch User, Suspend, Hibernate, Settings, and Exit.
+- **Configurable Commands:** Easily customize the commands executed for each action via the settings dialog.
+- **Lightweight and Efficient:** Designed to be fast and resource-friendly, perfectly suited for Openbox's minimalist philosophy.
+- **Modern GTK 4 Interface:** Built with GTK 4 for a modern look and feel.
+
+## Dependencies and Compilation
+
+ssdd requires:
+
+* GTK 4 development libraries
+* Glib 2 development libraries
+* gcc or clang
+
+### Easy Compilation
+
+Edit the `Makefile` or use the following commands:
 
-Using GCC:
 ```shell
-% gcc ssdd.c -o ssdd `pkg-config --cflags --libs gtk+-3.0`
+% make all     # Compile
+% sudo make install # Install to /usr/local
+% sudo make install PREFIX=/usr # Install to /usr
 ```
 
-Using Clang:
-```shell
-% clang ssdd.c -o ssdd `pkg-config --cflags --libs gtk+-3.0`
+### Manual compilation
+
+First generate the resources.
+
+```bash
+% glib-compile-resources resources.gresource.xml --generate-source --target=resources.c
+% glib-compile-resources resources.gresource.xml --generate-header --target=resources.h
 ```
 
-This produces the binary `ssdd` which you can place in your $PATH.
+```bash
+# Using GCC:
+% gcc ssdd.c resources.c -o ssdd `pkg-config --cflags --libs gtk4`
 
-## Configure Openbox to use it.
+# Using Clang:
+% clang ssdd.c resources.c -o ssdd `pkg-config --cflags --libs gtk4`
+```
 
-`% sudo nvim /etc/xdg/openbox/menu.xml`
+Place the `ssdd` binary in your `$PATH` (e.g., `~/bin`).
 
-Find the line with the standard Openbox Exit option and change it to
+### Integrate with Openbox
 
-`<item label="Log Out"><action name="Execute"><execute>ssdd</execute></item>`
+1. Edit your Openbox menu:
 
-The reconfigure Openbox to use the new setting.
+```bash
+% sudo nvim /etc/xdg/openbox/menu.xml
+```
+
+2. Replace the default Exit entry with:
+
+```xml
+<item label="Log Out"><action name="Execute"><execute>ssdd</execute></action></item>
+```
+
+3. Reconfigure Openbox:
+
+```bash
+% openbox --reconfigure
+```
+
+### Contributing
+
+Contributions are welcome! Feel free to open issues or submit pull requests.
