Issue 1508: Typed answer appears at the top and has no comparison
Showing a place holder instead of [[type]] location in question.
showing user answer instead of [[type]] location in answer.
Disabled showing keyboard when user want to answer type card.
Make soft keyboard return show the answer and hide the keyboard.
Use the typeNN CSS classes, make the typed text look more like in Anki desktop.
Also some clean up, mostly trailing whitespaces, or tabs..
