#375 JDBCCategoryDataset add execute(PreparedStatemet)

[Anonymous]

Description:
Need to redesign JDBCCategoryDataset class - add method execute(PreparedStatemet). In this version of class I move all result set processing logic from execute(Connection, String) to new private method - processResultSet(ResultSet). Next add required method execute(PreparedStatemet). Add constructor too.

Motivation:
New method should be use when query, from execute method, need parameters set by user. PreparedStatemet protect us from typically SQL injection attack - query string builded by hand.

Attachments:
- new version of class.
