Use POSIX-compliant read

Rewrite #520.
Using `read var?'prompt'` is wrong. It is ksh (and zsh) specific.

Since we cannot assume which sh is implemented,
we should write POSIX-compliant code.

Today's mutt-wizard does not support the XDG Base Directory specifications (https://wiki.archlinux.org/index.php/XDG_Base_Directory) because it says the user should be able to change the config, cache, data folders etc. using the environmental variables XDG_CONFIG_HOME, XDG_CACHE_HOME, and XDG_DATA_HOME, and instead hard codes the default paths ~/.config, ~/.cache, and ~/.local/share. My commit corrects this.
