Merge the preview mechanism for japanese with the standard one.

- Japanese is now handled by passing the option --latex=platex
    to the standard lyxpreview script. This is done in PreviewLoader.
  - Remove obsoleted file lyxpreview-platex2bitmap.py and the
    corresponding lines in the configure script.
