Create dialog service and Select Project dialog

[tjcouch-sil]

As an extension developer, I want to be able to ask the user for some information using existing dialogs in Platform.Bible so it is easy for me to get information from users.

We need to create a dialog service that allows extensions to asynchronously ask the user for a response to something. There are some things we need to put in this service:

• Select Project dialog
  • Share the UI with the open dialog Projects: Create stubbed Open Project dialog #359
  • Can provide a title, prompt, etc
  • Returns a promise to the project id that the user selected
  • Would look something like papi.dialogs.getProject or something

If the linked issues are done first, just connect them into this dialog service. If not, just make sure they are put in with the issue in which they are to be created.

I believe this is necessary for opening the Resource Viewer or Text Collection with a specified set of projects for the tech demo. @GlennPruitt

Good UX means dialog primary buttons should always convey an action to take ususally using a verb. A secondary button (if it exists) is almost always the verb "Cancel". That means we shouldn't have any Yes/No dialogs. Remember that users essentially hate confirmation dialogs, usually don't read them and just want to get rid of them as quickly as possible. So confirmation dialogs should only be used rarely when it is crucial. Rather than use a confirmation dialog it is better to allow the user to undo the action or easily recreate the data so they have confidence to discover what things do.

  • Type - how can we make this not circularly dependent with dialog service?
  • Component
  • Default width/height
  • loadDialog
  • saveDialog
• Genericize to papi.dialogs.get or something
• Mapped types
• rename to selectProject
• Revise file structure
