GDB-633 #time 20m

tailor: ActionList can take list in constructor

GDB-633
tailor: Add NoAction and Choice actions

Tinc: install init script on redhat

GDB-633

basically a workaround for
https://bugzilla.redhat.com/show_bug.cgi?id=682909

GDB-633

This is more robust and simpler than manually killing stuff.
Tinc: run chkconfig so tinc runs on boot on redhat
