Improving the Log tab

Fixes #190 by fefaulting to 1000 entries. This can be overriden in the %APPDATA%\Buttplug\config.json file:
```
{
  "buttplug": {
    "server": {
      "port": "12345",
      "secure": "False",
    },
    "log": {
      "max": "5000"
    }
  }
}
```

Fixes #185 by allowing multi-line selection and handling Ctrl+C to copy the log entries to the clipboard.

Fixes #187 by adding a Clear Log button, which clears the log list.
