Title: Allow inclusion of stack trace for Assert error messages to be config, with better browser compat

Allow inclusion of stack trace for Assert error messages to be configurable

```javascript
Assertion.includeStack = true; // enable stack trace to be included on error
```

Default value is false, resulting in less cluttered error results.
Allow user to configure this to true, to see stack trace to where error
occurred.

Added browser test and made tests compatible with browsers that do not support err.stack.
