Changes:

1. Align to current design
2. Dialog based navigation
3. LU intents been parsed and display with table view
4. Prevent leave page when got unsaved changes.

Sample Bot Changes:

1. ToDoLuisBot each dialog create a lu file.

Details:

1. nav All have table view, show all lu intents in this bot. text edit mode is disabled, cause it's multiple files
2. nav xxx-dialog have table view, show intents in this dialog. text edit can edit xxx-dialog.lu file.
3. column Define in Been used actually show this intent belong to which xxx-dialog.lu and been used in xxx-dialog or not.

I've found a pretty gnarly bug. When adding a new dialog file, it wipes away the intents on the LU page except for the main. Then, if you jump into edit mode and save, all intents appear again, but they are doubled!

Steps to repro:

1. Open LU page and notice the intents/dialogs
2. Switch to visual page and create new dialog
3. Go back to LU page and notice only the main lu file intents are shown
4. Edit any LU file then save
5. Click on "All"
6. Notice all intents are back, but are now duplicated!

Couple of issues I've found:

1. I am unable to publish the ToDoLuisBot sample due to empty lu files (Delete and Show). Adding a comment in them allows me to publish. The publish api is explicitly excluding empty files so I'm not sure what's going on here.
2. The runtime throws this exception: System.Exception: Reference ToDoLuisBotlu could not be resolved.

#2 i think it's because the .lu.dialog is not generated, but we still refer to that in Recognizer.

Add one comment from Marieke, we should get rid of the scroll bar of each intent, show all utterances at this version
