Fix NPE.

When entering the notification prefs sub activity without the increasing

threw an NPE because the handler wasn't yet constructed.

    Settings: Notification light(LED) settings

    This commit adds the ability to configure the Notification light
    color and pulse rate both for the default and a custom applications
    list.

    This work was done in collaboration with Marko Mihovilić (m1h4) who
    wrote the initial implementation as a stand-alone application and
    helped with the fixes below.

    NOTE: Google Talk notifications originate from the "Google Services
    Framework" so in order to override their settings you need to add
    this package instead of the Google Talk package.

Settings: fix led pulsespeedoff disable behaviour
Keep led pulsespeedoff disabled if pulsespeedon is
disabled.  This ensures that pulsespeedoff stays
disabled if onOffChangeable was set to false.  Fixes
problem where charged led pulsespeed off looks to
be configurable in the ui and thereby creating user
confusion.
