[worldKit-dev] Line label position and Initial label load

[Giorgio Plazzotta]

Then you mikel the Set <textinterval> to "0" was just the command I was 
looking for.

for the second ptoblem instead i think that something should be improved. 
Using the <singletextfield> to "true" could be acceptable only if this 
command was categorized but it isn't. Maybe it could be an enhancement for 
the developers.
