UI Improvements

[uniquePWD]

* Main Screen
    * Settings should be under the overflow button. Along with the help/FAQ and credits
    * Holding the cloud button should provide an explanation as to what it means
    * By default it should only show user apps
    * Upon showing system apps, they should be grouped together.
    * Filters should span the row (at the moment they only span two thirds of the screen)
    * Filter text ("Filtering by app type = user") shouldn't have the icon nor should it have a rounded border, the background shouldn't be a gradient.
    * There should be more (some) padding between each row
    * The title is missing from the main screen.
* App Settings
    * The check boxes should be far right
    * Permissions should be a drop down menu and should be text
    * There should be more (some) padding between each row
    * All permissions should be set at prompt by default
    * Permissions should be grouped General/Location/Media/Media/Network/Personal Data/Phone & Calls
    * There should be a way to set all the permissions on each page to a specific value where available
