let's make Impress crash less - SfxStyleFamily edition

Commit bcb41235deaf4b7ca90522bda3ba21a686819e6e - in addition to
introducing the enum SfxStyleFamily - inconsistently converted one
call of DrawDocShell::SetStyleFamily to use enum SfxStyleFamily
instead of a mysterious "5", but did not adapt all of the code that
extracts the SfxUInt16Item that subsequently extracts this value and
expects a number 0-5.

Since it's clearly inexcusably stupid to have 2 different public sets
of integers identifying styles, make the usage of the second "array
index" integers private to templdlg.cxx; the SfxUInt16 item now always
contains enum SfxStyleFamily.

(regression from bcb41235deaf4b7ca90522bda3ba21a686819e6e)
