currently the csv output is `\r\r\n` where the line terminator is `\r\n`
and the extra `\r` is probably being inserted from writing a dict to
csv. I get around this by changing the line terminator to `\n` to output
`\r\n` which will make it compatible with most spreadsheet apps.
- added Date and Account field to Saved Requests
- requests are now saved as dict()
old requests will be deleted!!
- Account field is hidden when only 1 account is available
- address line now follows the current_account
- saved requests is sortable, default sorted by date
- saved requests only shows request for current_account
New classes ScanQRTextEdit and ShowQRTextEdit.
Reason: dependencies on zbar availability and issues with the QRTextEdit constructor.
- ScanQRTextEdit needs access to the config (fetch camera). It needs to load
the zbar processor properly before trying to scan. Keeping a reference to
the processor in qrscaner fixes the crashes on windows.
- ShowQRTextEdit should not have access to scan_qr().
- no need to setReadOnly anymore. It is clear from the class name.
Show master pub keys now has a Combobox if multiple accounts are
available.
