Switched to blend4j 0.1.2
- pom.xml: switched to blend4j 0.1.2 because of issues with blend4j 0.1.1.
- LineCountExample, LineCount.ga, and Constants: added an example with a line, word, and character count workflow.
- FileUtils: added the createTemporaryFileFromURL method.
- ConcatenateExample: this workflow does not work on the Galaxy server at Vancis, so it now uses the central Galaxy server.
