Add descriptions to all choices in Sensor statements

[ZeroRin]

Describe the content or mechanics you are proposing.

Currently only some of the choices in the list have description (like @dead and @flag) Please add a description entry for all the choices.

Describe how you think this content will improve the game. If you're proposing new content, mention how it may add more gameplay options or how it will fill a new niche.

While most of these variables can self-explain, players don't speak English won't be able to understand them. Adding description entries will allow us to translate these things.

If possible, it's better to have a short translation word next to the variable name that does not require hovering over to show up

Before making this issue, check the boxes below to confirm that you have acknowledged them.

• [X] I have checked the Trello to make sure my suggestion isn't planned or implemented in a development version.
• [X] I am familiar with all the content already in the game or have glanced at the wiki to make sure my suggestion doesn't exist in the game yet.
• [X] I have read README.md to make sure my idea is not listed under the "A few things you shouldn't suggest" category.

making logic more accesible is a positive, good suggestion
