show error stack in console on uncaught exceptions

this will show something like this
```
[node-error 4:01:19 PM] [Launcher] uncaught exception at top level, exiting. TypeError: undefined is not a function
    at C:\Users\martinz\AppData\Roaming\Brackets\extensions\user\zaggino.brackets-git\src\Domains\processUtils.js:16:13
    at ChildProcess.exithandler (child_process.js:538:7)
    at ChildProcess.EventEmitter.emit (events.js:99:17)
    at maybeClose (child_process.js:638:16)
    at Process._handle.onexit (child_process.js:680:5)
```
on uncaught exceptions in Brackets console, instead of this
```
[node-error 4:01:19 PM] [Launcher] uncaught exception at top level, exiting. TypeError: undefined is not a function
```
