New: *Java Scanner* (closes #42).

* Based on JavaScript, does a good job, but may need more polish.
* Java::BuiltinTypes::List is a helper constant that contains 2389 Java types.
** The list was generated from TextMate's Java bundle with the help of SimpleRegexpScanner.
* I added the JRuby core classes as example code for testing (1.8 MB)

JavaScript Scanner:
* Fixed recognition of floats and algebraic signs.
** Still needs work - we need to distinguish i-1 from i+-1.

More changes:
* New: "SimpleRegexpScanner":http://murfy.de/simple-regexp-scanner
* Added new token class :annotation along with CSS styles.
** Should be useful for Python, too.
* coderay_suite warns if no scanner was found for this language.
* PluginHost#default can be called without parameter (will return default id)
