* I2PTunnel:

Browse Source 
- Display custom error pages for I2PSocketExceptions (ticket #788)
   - Tag I2PSocketException text for translation (no bundles yet)
   - Move methods from superclasses to I2PTunnelHTTPClientBase
   - Fix connect client error pages, but they aren't displayed anyway
   - Don't start I2PTunnelRunner threads in constructor (ticket #973)
   - Synch close() in I2PTunnelServer
   - Cleanups and javadocs
