Summary: performance optimization for Assert

Initial Comment:
I've made JUnit's central class Assert a tiny bit
faster by doing two things:

1) Using StringBuilder instead of concatenating Strings
for the error messages. StringBuilder is the thread
unsafe brother of StringBuffer, introduced in Java 5.
2) Using the factory methods for numbers, e.g.
"Double.valueOf(double)" instead of "new
Double(double)".  Quote from the javadoc: "If a new
Double instance is not required, this method should
generally be used in preference to the constructor
Double(double), as this method is likely to yield
significantly better space and time performance by
caching frequently requested values."
