Add easy to use text editor/configuration wizard to initramfs

[m-byte]

As some easier way of creating and updating the initramfs would simplify getting started and the instructions quite a bit, I came up with these two ideas:

1. add some easy to use text editor to the initramfs and automatically create the urnvr.conf file for users that are fine with the defaults
2. create a configuration wizard that is able to create/update this file as necessary

I believe option 2 would come with a significantly smaller size penalty. What are your thoughts?

After giving this some thought, I decided that I will write a small go program that replaces the init script. This program will include a basic ssh server, also eliminating dropbear.
