Application Config Demo

A boiler plate on how to do Application config the "Lazarus Way (tm)".

It includes:

• Setting up what properties to save on TForm.SessionProperties
• TINIPropStorage for TForm.SessionProperties property storage
• TFileExit action with different shortcuts for Windows and Linux
• The use of GetAppConfigFile() to get the app's default file customised for Linux/Windows
• A way to have different short cuts for exit in Linux(CTRL+Q) and Windows(ALT+X)
