Schedule SMS: Auto complete text box for contacts

[vaishalok]

• Should prompt suggestion as soon as you type even a single char
• Should properly delete entries if you tap on them (There is issue in deleting last item)
• Should not highlight the edit text (modify design)
• When user is entering number using keyboard, don't create span if number contains anything other then numeric, dash(-) and plus (+). If plus is present it should be the first character.
