Bug 1020109 - Cell broadcast search list is not set correctly

The current code attempts to protect against empty objects incorrectly
since empty arrays are truthy in JavaScript. The result is empty objects
get passed to SettingsLock.set() which seems to break all subsequent
settings change observers.

Bug 1021777 - Set multiple search engines by default
Bug 1022450 - Don't show the "WAP Push Message" string in the header when opening a message
Bug 1020744 - [Dialer][Flame] Enter more than 19 digits in dialer, back delete button moved couple pixels to the left
Bug 1022733 - Entry points lost their splash screen/overlay icons

The origin for applications that have different entry points (e.g.,
Dialer and Contacts are the same application, Communications) also
contains a pathname, so we need to remove that from the origin before
appending the splash icon path.
