Blimp: Added spinner to text input dialog

Added a spinner (ProgressBar with indeterminate style) to the text input
AlertDialog. The spinner is shown when user hits enter/OK, and is
dismissed on receiving a hide IME request or if the user hasn't changed
the text or cancelling the dialog through back button/touching outside.
During submission, the EditText background changes to a dotted line.

In an unrelated change, fixed the IME editor options (following similar
structure as ImeUtils.java). This enables multi-line input for text area.
