tdf#148491 make Imagemap dialog consistent with Description

  This patch is part of a general effort to use
  "Text Alternative" consistently in the UI.

  The control names in the Description dialog for
  Imagemap and the Imagemap dialog were both changed
  to "Text Alternative". Tooltips were also added
  for "Text Alternative" and "Description."

  No change was made to the extended tooltip for
  "Description", because this field is not exported
  to HTML at present (tdf#149013)
