* Rebuilds the Windows x64 binary of the PortAudio support from its latest source/r7982.
  * Other recent changes in earlier versions:
  * - Opens the PortAudio streams with a valid framesPerBuffer value in order to make it possible to use the pseudo-blocking PortAudio stream interface implemented in r7982.
  * - Update check detecting wrong password on secure locations.
  * - Implements the blocking PortAudio stream interface on top the non-blocking PortAudio stream interface in order to make it possible to use the DirectSound PortAudio implementation on Windows and to decrease the input/capture and output/playback latency.
  * - Fixes a warning about isspace being implicitly declared.
  * - Fixes NullPointerException in MetaContact.getDefaultContact().
  * - Limits contact list selection to a "single selection" to reduce row size problems coming from the multiple selection behavior.
  * - Reverts the recent changes to up2date.exe because, as discovered by Damian Minkov, it breaks the build.
  * - Fixes 'Check for Updates' on Windows to start the setup as an update, not as a new install. The fix should be in effect after it is installed i.e. the setup may be started a new install once but it should start as an update afterwards.
