Bug #6286: Add Exception#format method

----------------------------------------
It would be nice if Exception class could be extended by #format method (or method with some more suitable name), which would provide the same formatting as is standard output of Ruby exception, e.g. 

boomtest.rb:18:in `go': boom (RuntimeError)
  from boomtest.rb:34:in `foo'
  from boomtest.rb:36

Currently, this formatting is done by error_print function from eval_error.c. Unfortunately this method is just Ruby's internal.

Please note that there exists exception_string gem, which add similar method [1] to the Exception class.
