Split out data pieces from hostname
Split out data pieces from hostname

Rename _lp_hostname() to _lp_hostname_color() as it doesn't do any data.
Move calling of _lp_hostname_color() to _lp_theme_activate().
Break out _lp_connected_display() and _lp_chroot(). Both are very
simple, but maybe someone will want to add more checks.
Fix chroot not being printed if local and LP_HOSTNAME_ALWAYS not set.
