Switch to more liberay CC0 public domain license

Reworked README and xmlx/entitymap.go. Now includes conversion of named xml entities instead of just numeric ones. Eg: π and π to a unicode character and vice-versa. It also came to my attention that lack of a proper opensource license might put people off of using this package. I therefor added a 1-clause BSD license under which this code now falls.

fix: String() handled ns prefixes incorrectly Previously parsing a document like this: <root xmlns:foo='http:/example.org/foo' foo:bar='1'/> Would produce an incorrect document when turning it back into a string: <root xmlns:foo='http:/example.org/foo' http:/example.org/foo:bar='1'/> This patch fixes this by implementing a proper lookup for namespace prefixes.

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.
