Added Suite Tab

Also some additional support for testing Lambda functions.

Tester panel update

When you submit an input, the input panel does not clear the text. It does a "select all" on it. If you want to submit new text, you just type it as normal. If you want to re-submit what you just entered, you can just hit enter or send.
The display of the current transcript is now a list. Double clicking a list entry will populate the input box with the text from that submission.

Surfaced AppID and UserID

You can now set and track the Application ID and the User ID.

Script playback added

You can now record a session, mark it up, and play it back.

Many usability improvements

The history view can now be toggled to reveal all aspects of the interaction.
Application definitions may be stored on a MRU list and cut and pasted from the clipboard.

Several usability improvements

UI does a better job of remembering what product you were working on.
The enablement of the buttons in the Testing tab is improved. You can now send an intent without first starting a sessions. This lest you mimic the launch option from the Echo.
As you type in text, the box below tells you the intent and slots it will parse the string into.

Works with Hello World app

EchoSim can now send queries and receive responses to the Hello sample app included with the Alexa AppKit. It's ready to be tried out on something more substantial.

Bare minimum, script generation

This contains the bare minimum. It can read an intents file and a utterances file, and then create a brain dead simple manual test script from them.
