Update kinput2 to 3.1.

Major changes from version 3.0 to 3.1:

* Kinput2 now supports ATOK.  The source code is kindly contributed
  by Justsystem Corporation.  Thanks!
  To compile for Atok, define symbol `UseAtok' in Kinput2.conf.

* Minimum support of Wnn7 is implemented.

* Two IC attributes, XNPreeditState and XNResetState both of which
  are introduced by X11R6, are supported.

* Kinput2's `egg'-emulation is improved.

* A workaround for bugs in some Xlib implementations has been added.

* Previously, when kinput2 cannot connect to jserver, kinput2 seems
  to be frozen (actually it keeps retrying).  Now kinput2 beeps and
  ends conversion in such a case.  The next time you start conversion,
  it tries to connect again.
