fix(handlers/main)!: Change exit key to `q`

`Esc` is bound to exit a deeper mode (like `insert` or `command`) and
return to `normal` mode. This however is rather inconvenient,
when `Esc` also exits Trinitrix in general, as spamming `Esc` then
becomes impossible.
This changes also puts Trinitrix more in line with vim (although vim
does not allow exiting with `q`).

BREAKING CHANGE: To exit press `q` instead of `Esc`.
