Uncommented SearchView code for Infinum intervention
Added onResume method

OnResume now displays the last fragment that was viewed in MainActivity.
Also updated the way the title for the activity is changed.
Updated name for the settings fragment into 'Settings'
Update the way the alert message is retrieved
Created a simple SettingsFragment

For now it only enables the reset of the selected city and institution.
Updated MainActivity to display the new SettingsFragment
Updated IntroActivity to handle the reset

And by handle I mean just skip the first page...
