Add support for setting environment variables in Alt+F2. Such as LC_ALL=C Thunar

Hello, everyone.

Often I need to run a GUI application specifying some env variables, because some apps require them to work correctly. My particular example being:

LC_ALL=zh_CN.utf8 wine /home/lockywolf/.wine/drive_c/Program\ Files/Tencent/WeChat/WeChat.exe

However, xfce4-apprunner doesn't support such commands.

If someone could help with it, would be great.
