• improved completion suggestion for db schemata

- if user typed "foo." and there's an unique schema path regardless cases (like there's an item Foo) show the content of the path Foo
- now getUniqueDbIdentifierFor:term returns an array of found type (db or table) and the found string to handle case better for completion
• tried to speed up the search in the navigator by using a NSPredicate
• [MCPConennection allKeysofDbStructure]
- fixed issue while returning if allKeysofDbStructure == nil
