Fix GDL2, EOSQLQualifier (EONotQualifier -schemaBasedQualifierWithRootEntity:)

[Georg Fleischmann]

Hi,

here is the implementation of [EONotQualifier - 
schemaBasedQualifierWithRootEntity:]
and a fix in [EOSQLExpression -sqlStringForNegatedQualifier:] to make  
it work.

* EOAccess/EOSQLQualifier ([EONotQualifier - 
schemaBasedQualifierWithRootEntity:]): implemented
* EOAccess/EOSQLExpression (-sqlStringForNegatedQualifier:): get  
sqlStringForSQLExpression of the right qualifier

Best wishes,
Georg Fleischmann
