Standardize messageBox handling on app

[tupaschoal]

There were several places using showMessageBox and showMessageBoxSync throughout the app, but they all called them differently and with different names. This centralizes and standardizes them all so that all dialog interactions feel consistent:

• 3b63618 and 4427452
  Just making the names actually consistent with what they do
• 3f129c7
  Allow people using showDialogSync to customize the dialog further
• 169c0f0 and bae0497
  Make files using showMessageBox* use the aliases of window-aux instead.
• 08287cf
  We know this makes mocks work on tests, so let's prepare for the day these are mocked :D
• 1ab2d3d
  No need to specify titles, they will come from the utility functions themselves.
• bce1224
  All dialogs will now have the "Time to Leave" title, with the previous title being a blue title inside the dialog and the previous message further down:
  
• c822b96 and 38cacec
  I noticed several dialogs were doing things upon being closed on the X, which should never happen, so I made sure all of them had cancelId set to the same defaultId which is the action that won't do anything.
• 3222607
  Made dialogs use the info, warning, ... icons instead of the TTL app icon, which previously felt weird
• 24c6850
  Small bug fix
• be1a792
  Getting rid of redundant option to "cancel" when the option to say "no" is already there.

@tupaschoal I see sometimes we use Yes/No buttons on the footer and at other times big buttons with please and thanks. Maybe we should just use the footer buttons and make the text more neutral?

Great improvement 😊
