Add template for svdrphosts.conf

you can define additional hosts or subnets (default is to allow access
from localhost) in svdrphosts.conf by
creating a list variable vdr_svdrphosts - e.g. in host_vars/localhost
or in group_vars/all:

vdr_svdrphosts:
   - 192.168.0.0/24

also cleanup some of the structure in Manual.org and update Manual.html
