Using getDBConnection rather than pass connection as a parameter.

Using getDBConnection method rather than a parameter.

Change the prototype of method getUniqeID

made a ton of changes related to keeping oracle SQL code out of the main classes. fixed a bug where the timing of the index thread was off so when it went to index a document, the document was not already in xml_documents thus breaking the FK relation between xml_documents and xml_index. I think that bug might be the reason for the blank resultset screens in morpho. made the postgres implementation much more robust.

changed all mentions of DBAdapter to the new name AbstractDatabase

rename the DB* classes to:
AbstractDatabase
OracleAdapter
PostgresqlAdapter
SqlserverAdapter

included new function that returns db specific non-null function name

- new db adapter for MS SQL Server
- changed the getUniqueID(conn, tableName) to return the last generated by the db unique ID
instead of generating unique ID first by the appl and then supplied to the insert,
because SQL Server doesn't have capabilities
unique ID to be generated on the client and then supplied to the insert.

changed the getDate method to getDateTime and changed the return
string in the postgresql implementation to "now()" from now()::date

change the method name getDateString() to getDateFunction()
return "now()::date" in the DBPostgresql implementation of that method
