Move SimpleExport to libardour, add Lua bindings

Browse source 
This allows to export a session from the commandline tool

```Lua
AudioEngine:set_backend("None (Dummy)", "", "")
s = load_session ("/path/to/session", "snapshot")
assert (s);
e = s:simple_export()
assert (e:check_outputs ())
e:run_export ()
e = nil
```
