Some love for the Cpaster plugin

- Put classes into namespace.
- Fix settings not storing the selected protocol.
- Refactor settings by introducing standard handling.
- Create PasteSelectDialog class and fix list/refresh handling.
- No longer stuff the QListWidget into the protocol for listing, wire
via signals.
