[enhancement] Quote messages

In huge conversations it is beneficial to be able to quote messages, so the recipient can retrace which answer belongs to which questions. In other messengers there is usually a little preview of the quoted message and when clicking on it, the messenger jumps to the point in the history where the message is (So it is possible to also click here on the quoted message and have something like a thread in a conversation) To have easy access to the quoting mechanism, you can usually swipe messages to the right edge of the screen and then this message is selected for quoting.

So features:

• Quote message through context menu and swiping message to the right.
• Show quoted message above the input field while answering the message
• Show preview of quoted message above the answer
• When clicking on the quoted message, jump to the original message
