Org reader: fix smart parsing behavior

Parsing of smart quotes and special characters can either be enabled via
the `smart` language extension or the `'` and `-` export options. Smart
parsing is active if either the extension or export option is enabled.
Only smart parsing of special characters (like ellipses and en and em
dashes) is enabled by default, while smart quotes are disabled.

This means that all smart parsing features will be enabled by adding the
`smart` language extension. Fine-grained control is possible by leaving
the language extension disabled. In that case, smart parsing is
controlled via the aforementioned export OPTIONS only.

Previously, all smart parsing was disabled unless the language extension
was enabled.
