Replace all snackbar popups with modal dialogs

[cckozie]

The snackbar popups are too un-intrusive and are easily missed by the user and are sometimes hidden under the soft keyboard. They all should be replaced with popups that the user needs to dismiss or otherwise act upon.

@cckozie this is more of a design aspect rather than Q/A. This needs to go through ts-requirements.
