Maintenance of Multipress input method by Openismus GmbH:

* modules/input/gtkimcontextmultipress.[ch]: Clean up the code
a bit to follow the GTK+ coding style more closely.  Fix the code
to emit "preedit-start" and "preedit-end", too, rather than only
"preedit-changed".
(GTK_IM_CONTEXT_MULTIPRESS*): Rename incorrectly spelled macros
gtk_im_context_multipress*. Shouldn't break API or ABI as it's
only used internally.
* modules/input/immultipress.c: More cleanup,
* modules/input/README.multipress: ditto.
