Recursive handling for command line flags

Every struct in a NodeConf with `lopt:"foo" set is now added as a
command-line flag with the RecursiveCreateFlags call. For maps a struct
with the key UNDEF is added so that it can be parsed out.

As the flags for the command-line need variables which hold the values,
for every map an element map[UNDEF] is added.  When now calling the
internal add, these map element can be filtered out and replace by the
given name. (e.g., --netname)

* rewrote node/profile add for recursive functions
* rewrote node/profile set for recursive functions
* rewrote node/profile list for recursive functions
