Added blur background effect and panelOffScreen option.

<com.sothree.slidinguppanel.SlidingUpPanelLayout
    ...
    sothree:umanoBlurBackground="true">

<com.sothree.slidinguppanel.SlidingUpPanelLayout
    ...
    sothree:panelOffScreen="true">
...

If the panelOffScreen attribute is true in the xml, the panel will keep the sliding until it's located off screen. If gravity=bottom, it will be above the screen (see gif below).
