Fix the value fetcher to deal with NT_TEXT nodes.
Due to the introduction of the NT_TEXT nodes, all of the simple value fetchers broke. To fix, make a GetValue function fetch all NT_TEXT nodes for NT_ELEMENT nodes, and put them together, using string.TrimSpace to remove extra, maintaining compatibility. Then change the .S function to use GetValue to fetch a node's content. Also, make all the other value fetchers use .S to get a string representation to convert, centralizing the implementation. Use .S to centralize the handling of a not found node. Also, implement a series of tests to verify all the fetcher's functionality. The test is based on the test produced by Tim Jurcka.
