Fix scene name unicode save error

[p0psicles]

How to reproduce the issue:

1. Run medusa on windows. I've used Windows 7
2. Make sure used locale is x.cp1252
3. Add Naruto Shippuuden
4. Now you can open the show in displayShow and editShow just fine.
5. Go to editShow and save the show, you should be redirected to displayShow
6. You'r getting a mako 500 error page.

@labrys @medariox your both the unicode guru's here. Is this the way to solve this? It seems to work for me now? Still have to test on other linux with utf8.

[medariox]

The question is: why is scene_exceptions a list of encoded items and not decoded items (like it should be)? It would be best to decode scene_exceptions at the "source". About decode('utf-8', 'ignore') I would personally prefer decode('utf-8', 'replace'), but - until we finish the transition to unicode everywhere - there is nothing wrong about it.

It should be unicode encoded right? Else you can't display the chinese chars right?
I personally think it's an issue with tornado, it is processing the post by default as encoded in str(). While it should be encoded in unicode.

[medariox]

Yes, I would say the problem is that when you add an exception that contains chars that your locale doesn't support (in your case cp1252) the join() that takes place in displayShow tries to decode them with the default locale, but fails.

I've PR'd his one towards fix-bwl. When that's merged, i'm going to create a new one for dev. In the mean time, we can discuss here.
