Search case insensitive

[sergiorgiraldo]

V 0.13

I have this on my config.toml:

[[columns]]
kind = "Command"
case = "Insensitive"

[search]
case = "Insensitive"

When looking for 'espanso', it should find both but only matches the lowercase. If looking for 'Espanso', only matches the uppercase. It should match both if case is insensitive.
