Revert "Remove smiley support"

This reverts commit c7c68dba4f3440f234f65eef579f9aaa82682f8c.

It seems that the smiley support has been removed by a Google Dev (Tom Taylor)
without any explanations:
    https://android.googlesource.com/platform/packages/apps/Mms/+/c7c68db

This modification gets the smiley back:
 * ASCII Smileys are converted to images in all received/sent messages.
 * A new menu entry (Insert smiley) is available in the menu of a conversation
   view (ComposeMessageActivity).

I also added this support in QuickMessage too (by parsing the message
just before sending it to the TextView).

Hide "Insert smiley" if emoticons are disabled

There's no point in having "insert smiley" option when
graphical emoticons are disabled.
I still hate these emoticons.

Mms: disable SplitActionBar

This makes the UI more consistent with newer Email app look.
