* Fix. Support MOH app on Windows.
* Use `path_join` to build mask
* Fix. Build path on Windows.
Main problem is on line like `path = '/'.trim(...),'/');`
On windows it produce path like `/c:/...`.
I also rewrite code to use`path_join` to build all paths.
So there no needs to tests either path end with path separator or not
you always can just write `path_join(a, b)`. `a.'/'.b` is not always produce
correct result and it require some additional works.
* Fix. Get correct MOH settings to display in Web UI.
