Format change at "Mobile network type" value

Remove "network type Number" from "mobile network type" value
at "About Phone > Status".

For example value "UNKNOWN:0" became "UNKNOWN"
(if value is "UNKNOWN", the word is localized)

The number ":0" did not add much value to the user.

Makes the add button for new APNs appear in the action bar.

The APN add button (a plus sign) now appears in the action bar if possible. The APN list interface is now more consistent with the WiFi list interface. Previously the user had to press the 'Menu' hardware button or the three dot button on the screen in order to reveal the actions.

Grey out settings icon when it is in disabled state

If engine is not active, its settings icon is disabled in
Settings > Language & input > Text-to-speech output screen.
Currently, settings icons for all TTS engines are shown at
the same opacity. This fix dims settings icons of not-selected
engines.
Make sure that more than one TTS engine are installed on the
target, for e.g., Google Text-to-speech Engine and Classic
Text To Speech Engine (SVOX Classic TTS).

Additionally, since setAlpha() is used in multiple places within
Settings package, moved DISABLED_ALPHA declaration to Utils.java
in order to have single point of reference.
