- increased default peer ping time from 2 minutes to 1 minute

- filtering out too old peers when reading seed lists (limit is now 240 minutes)
- added concurrent host names resolving in front of the http client because the http client uses the java built-in DNS resolve which is not multithreading-safe (i have seen deadlocks in thread dumps showing that this bug in jdk is still there)
