Title:
  Invalid ADC commands sent via UDP will crash the app

Bug description:
  The AdcCommand parsing function will throw ParseException on invalid
  commands:
  https://sourceforge.net/p/dcplusplus/code/ci/default/tree/dcpp/AdcCommand.cpp#l37

  However, SearchManager (UDPServer in AirDC++) won't catch those
  exceptions at all:
  https://sourceforge.net/p/dcplusplus/code/ci/default/tree/dcpp/SearchManager.cpp#l286

  
  As a result, you should be able to crash the app by sending the following raw text to the UDP port: 

  ARES T\n

  (I used https://packetsender.com for testing)
