java/intellij: 15.0.3 -> 15.0.4

• Thanks to Jiri B <jirib@devio.us> and Roman Shevchenko [1] for contributing a libinotify-based replacement for IntelliJ's fsnotifier. IntelliJ now has native (faster) file notification support on FreeBSD (and OpenBSD).
• Because of remaining problems with watching large trees with libinotify [2], fsnotifier is still disabled by default.
• fsnotifier and native pty4j support need to be compiled. In the interest of reducing port complexity, the building of pty support and fsnotifier is moved to separate ports:
  • java/intellij-pty4j
  • java/intellij-fsnotifier
