Summary: Range.insertBefore() and Range.delete() fail with
Unicode characters

patch to Range, FileInformationBlock, and TextPiece to address problem
described above (see bug text for limitations of patch)
When OpenOffice.org creates MS Word 97 formatted *.doc files, it uses Unicode.
When Range.insertBefore() and Range.delete() are used with these multi-byte
representations, a couple of different problems occur:
1. The indices are not calculated correctly so delete() seems to delete
arbitrary characters or fail with IndexOutOfBoundsExceptions
2. For the same reason, insertBefore() seems to insert text at an arbitrary
position and subsequent operations fail with IndexOutOfBoundsExceptions
There is a marginally related problem with these operations; they do not update
FileInformationBlock.CCPText, and this throws OpenOffice.org for a loop. It
stops reading character text prematurely and renders document headers and
footers incorrectly.
(see attachment for a partial patch to address both problems; note that the
patch does not address overloaded versions of insertBefore(), nor does it
address insertAfter())
