OUT-1177: The margin on the left of the pEp Toolbar now is always applied in explorer windows regardless of if new Outlook vertical pane for Apps is visible or not. In inspector windows such as compose, reply, reply all, forward, the left margin is never applied as the new Outlook vertical pane for Apps is only used in the explorer windows. Also, the starting position for the pEp Toolbar content is now always slightly shifted to the right with respect the pEp Toolbar's title so Toolbar content and title are no longer going to be horizontally aligned.

OUT-1226: Change display settings toolbar pop up spawns too many times. A new popup window was being open every time a display setting change was detected and also in specific circumstances such as when plugging in or unplugging a monitor or also when the currently logged-in user had changed (switching user, even to the same). Now, before opening the popup dialog, we check if it is already open and if so, we don't show it again so we avoid showing it too many times. Also the popup dialog is only shown when display settings are explicitly changed by the user. We ignore now those events caused by plugging in/unplugging a monitor or when switching user (even to the same).

OUT-1213: We treat both "Trusted (secure and trusted)" and "Trusted and anonymized" the same. After confirming the trustwords and fingerprints for the recipient from the Trust Wizard, we get "Trusted and anonymized" rating from the engine for the next emails we receive or compose from/to that recipient. Otherwise, if we don't treat the "Trusted and anonymized" rating, we will not get any icon nor text status displayed in the pEp Toolbar.
