Merge pull request #6 from Gottox/master

install bootloader on -p udroid-u2
mkrootfs: make platform argument mandatory, install <platform>-base pkg automatically.
mkimage: guess platform automatically, add new options to set fstype and boot fssize.
README: update.
installer: copy host void rsa pubkey to the target rootfs.
installer: added basic wifi setup via dhcpcd (only WEP and WPA/PSK for now).
installer: add a network option in main menu.
installer/mklive: make sure to install dcron rather than cronie.

dcron is smaller and only has a libc dependency.

cronie is selected because it appears alphabetically before in the repo index.
Revert "installer/mklive: make sure to install dcron rather than cronie."

This reverts commit 1ccbe860517465abe70d8b450fa6cae69ab4b691.

I'll fix this properly via base-system.
mklive: switch to xbps-uchroot(8); bye bye systemd-nspawn.
mklive: remove unnecessary steps.
mklive: avoid void-{artwork,mklive} dependencies on system.

I'm starting to make the scripts distro independent; this is just
the first step.
README.md: sync with reality.
mklive: redirect to logfile when reconfiguring locales; load loop kmod too.
