Grep complains about stray backslash with weather enabled

[mklein994]

When I run the sunpaper command as a daemon with weather enabled, I get a warning about a stray backslash:

$ sunpaper -d
grep: warning: stray \ before "
grep: warning: stray \ before "
grep: warning: stray \ before "
grep: warning: stray \ before "
The Sunpaper daemon has started -- use sunpaper.sh -k to stop it.

I'm pretty sure it's because the grep string has some unnecessary escapes:

$ echo '"foo"' | grep '\"foo\"'
grep: warning: stray \ before "
grep: warning: stray \ before "
"foo"

Specifically this line is suspect: https://github.com/hexive/sunpaper/blob/main/sunpaper.sh#L637

yeah, that line should probably have single quotes:

weather_main=$(echo "$weather_info" | grep -o -e '"main":"[a-zA-Z]*"' | awk -F ':' '{print $2}' | tr -d '"')

thanks for letting me know!
