Create a list of all current configurator options

[WallK]

We should list all the features (options) available in current Zenity configurator This list should have functions or option names from bash scripts Options should have:

• setting_file
• setting_name
• system
• section (optional)

[WallK]

Additionally we need to put:

• Input field for SteamGRID (?) API key

Radiobuttons:

• Prefer Animated Images
• Allow NSFW images

I would add even short description, input and output so we can add them in the wiki in the development section.
