commit c61a3ff06e57c7c324e69419aaed0f92b37befd0

add indexOf family of function to OUStringBuffer
it is fairly common when converting String to OUString
to find code that search for thing and replace/delete
these things... the later need OUStringBuffer, the former
OUString.
This add the search feature provided by the indexOf family
of function found in OUString, into OUStringBuffer
