[Libreoffice] [PATCH][EasyHacks] Remove some use of svarray stuff in SwScriptInfo

[Nigel Hawkins]

Hi,

The attached patch removes one use of SvBytes and SvXub_StrLens from
SwScriptInfo.

There are still other uses in there to be replaced, but the bits don't
interact very much.

Changes under LGPLv3+/MPL

Nigel.
