Mapserver native oracle connection should not use ORACLE_HOME -parameter

[Jukka Sirvi ö]

Hello!
MapServer native oracle connection uses ORACLE_HOME enviroment variable,
variable should point to client installation directory. If the main
database (and probaply also other oracle software, for example AS and/or
Oracle Lite) reside in same hardware then this kind of use of this
specific enviroment variable can cause problems.

My opinion is that Mapserver should work independently from ORACLE_HOME -
enviroment variable? Comment's?
