Upgraded privoxy to 3.0.3

--------------------------------------------------------------------------
ChangeLog for Version 3.0.3:
--------------------------------------------------------------------------

- Fixed yet another two memory leaks. Process growth looks stopped now.
- Further tightened security against malicious toggle-off links.
- Excluded text/plain MIME types from filtering. This fixes a
  couple of client-crashing, download corruption and
  Privoxy performance issues, whose root cause lies in
  web servers labelling content of unknown type as text/plain.
- Assorted fixes for POSIX compliance, signal handling, graceful
  termination, compiler warnings, OSX support, Win32 systray,
  error logging, hostname wildcards, correct detection of NetBSD.
- Workarounds for client (iTunes etc) and server (PHP < 4.2.3) bugs
  including the notorious "blank page" problem.
- Various filter improvements; most notably the unsolicited-popups
  filter became less destructive
- Major revamp of the actions file
