sidebar 2.0

    this is a very lightweight version of ribbon that i plan on adding to and developing
    for vanir specifically. future plans include adding navbar keys, option to show apps,
    timeout options, gravity settings, notification expander, clock, notofication counts.
    eventually i want it to be an alternative phone UI in which the normal navbar & statusbar
    are hidden.

    the original patchset is based off of the open source sidebar app and pulled from a
    github by 0xD34D.

    PS2: fixed
