UiLibs and nested dialog panels coming in 5.6

[barrymavin]

If you have been following the roadmap you may have noticed this which is coming in 5.6 next week.

• New App UiLibs. Design pages visually then add them to the App UIlib enabling them to be used with Lianja.showDialog() and Lianja.showDialogPanel(). Check the page attribute "Register in UIlib". The pages are not included in the pages menu but can be used with dialogs by specifying "page:pagename" as the file name.
• DialogPanels can be be shown on top of existing ones. So, for example, if a page in the UiLib contains a grid section, then editing a row in the grid will overlay the grid with the "EDIT FORM" and clicking "Done" or "Cancel" will switch back to the previous DialogPanel i.e the grid section. This provides smoother UI transitions and a better mobile experience when screen size is limited.
