* Add `InvitePeopleState.sendInvitesAction`
Keep track of the progress on sending invites with a new state property.
* Keep `RoomInviteMembersView` open until invites are sent
* Sync strings from localazy
* extend `ProgressDialog` to support custom content
For my current design, a simple text element is insufficient. I extend
`ProgressDialog` to give more flexibility over the content of the dialog.
* Show progress dialog while invites are being sent
* Add new ProgressDialog previews to the naming exceptions list
* Update screenshots
