IWBootstrap as part of IW15

[jeroen.rottink]

I just upgraded from IW14 to IW15 (paid). Because I used IWBootstrap in IW14 I now went for the included IWBootstrap version.
First stop is to see if everything is still working. I used the (old) IWBSDemo for this. 
This demo isn't working anymore.

• Some compile errors 
  EscapeJsonString changed into TextToJsonStringProperty (fixed)
  IWBSCustomEvents.TIWBSCustomRestEvent.RestEventPath Don't know how to solve this so kept it disabled
  
• AV after running the application and starting the first session
  Seems to do with initializing TIWCompressor (fixed)
  
• Starting Fishfact demo gives an error
  
• File download by ajax is not working anymore
  
• Closing the modal dialog (TFrame) from Dialogs/Alerts gives a javascript error 'Cannot read property 'IWRelease' of undefined'. Can be that this was always the case. Not sure.
  

To get people using these 'new' pieces of IW a good demo would be an invaluable starting point.
Maybe a modified and working version of this demo can be published on GitHub.
