Oracle WKTEXT Translation — at Version 5

Description (last modified by warmerdam)

The following WKTEXT value from Oracle is not handled properly in OGR bccause the PROJECTION[] name has a space in it. We need morph to/from oracle methods in ogrocidatasource.cpp to remap projection names and other identified oddities of Oracle format. 

PROJCS["GK Zone 4 (DHDN)", GEOGCS [ "", DATUM ["", SPHEROID ["Bessel 1841",
6377397.155, 299.1528128], 582.000000, 105.000000, 414.000000, -1.040000,
-0.350000, 3.080000, 8.300000 ], PRIMEM [ "Greenwich", 0.000000 ], UNIT
["Decimal Degree", 0.01745329251994330]], PROJECTION ["Transverse Mercator"],
PARAMETER ["Scale_Factor", 1.000000], PARAMETER ["Central_Meridian", 12.000000],
PARAMETER ["False_Easting", 4500000.000000], UNIT ["Meter", 1.000000000000]]

I see the DATUM also has a bunch of unlabelled numeric parameters
were are presumably TOWGS84 values.  It would be nice to handle them properly
too.
