Convert RPC console to QTextEdit instead of QTableView

Browse source 
* This allows copy/pasting whole or partial messages
* Handle output more consistently in console
    * No more scrollbars-in-scrollbars: by setting per-pixel scrolling on the table, cells can have any height
* Decorations for "request" and "reply" are changed to the txin and txout icons instead of colored squares
