Replace QInputDialog with custom dialog for queriesquery-dialog

Recent commits allowed multi-line input while reusing the QInputDialog
object already defined by Kristall. However, QInputDialog lacks a way to
access its QPlainTextEdit directly, and therefore set the wrap mode.

Since QInputDialog does no wrapping, it is inconvenient for writing a
long text (think of social media sites such as BBS or Station).
Therefore, a custom QDialog-derived class, namely QueryDialog, has been
provided.
