Nits (easy fixes)

[mbo...@gmail.com]

Could we please get the non-ASCII character removed from DefaultVisitController.java:

  https://github.com/bolinfest/plovr/commit/a956438fb475422044f4e3f4cf9a2e6c4f0d5275

And also update the .classpath file to match the version of Guava in the lib/ directory:

-       <classpathentry kind="lib" path="lib/guava-10.0.1.jar"/>

+       <classpathentry kind="lib" path="lib/guava-12.0.jar"/>

For bonus points, could we update the project to Guava 14.0.1?

Thank you,

Michael
