Allow for easier querying of collected knowledge

[tpwo]

I noticed that I started to use pyzet more and more just for grepping for already saved knowledge rather than adding new stuff, and went with design to streamline this kind of usage.

The new proposed behavior is a bit similar to git -p flow and is implemented by pyzet query. It seems to work quite good when you're looking for something you know it's in your ZK, but you don't remember exact details.

I wasn't happy enough with them, so I never merged them to main, and they're in add-query branch. Instead, I'll create a PR as main has newer commits at this point, and rebase would be painful.

Demo of currently proposed behavior:

$ pyzet query
Hello there! What's next? [p,e,d,g,G,a,q,?] ?
p - print one of matching notes
e - edit one of matching notes
d - delete one of matching notes
g - grep for other notes
G - grep for other notes (case insensitive)
a - add a new note
q - quit
? - print help

# Bash export function instead of alias

Aliases are great but they don't work in subshells and external programs
like Vim. An alternative to alias is a Bash export function.

It's just a plain function that we later export with `export -f <name>`
command:

    function foo () {
        <some-command> "$@"
    }
    export -f foo
