Update nc_arch.py

Added Antergos, Linaro, Manjaro, Archbang and Bluestar to the accepted list of Arch derivative distro's to avoid a "Backend Required" error
Removed Linaro

Make Step2.xml more welcoming English

The first run screen is vital for making new users feel comfortable and unthreatened, so they'll continue, finish the install and keep actually using arkOS / Genesis. Accordingly I've updated firstrun step 2 messages to be more friendly and accessible to low tech users. Phrases like Unix and SSH can be introduced later, such as in a message telling users that have just set up SSH that they can use their standard username / password to log in.
Humanize the Step3.xml language
