When making assertions about complex objects, Jasmine's
failure message are sometimes gigantic and difficult
to read because the string representation of an object
contains all of the methods and properties in its
prototype chain. This commit causes the pretty printer
to only display on object's own properties.
Currently, jasmine's pretty printer traverses objects
to 40 levels of nesting. If an object is more deeply
nested than that, an exception is thrown. I find that
after a few levels of nesting, the output becomes
difficult to read. The process of serializing such
deep objects also sometimes crashes the browser or
causes a 'slow script' warning.
This commit exposes a 'MAX_PRETTY_PRINT_DEPTH' option.
It also causes the pretty printer to skip over
parts of an object that are nested to deeply by simply
printing out 'Object' or 'Array', rather than throwing
