Clean url router

[mediaminister]

This implements the new router design as discussed in #103

Oh god, I broke it really good. Need to think about how to add refresh in this new scheme.

[dagwieers]

Let me offer a fix for this the coming week.

I think we can use the existing scheme and merge it with the CACHES database as it was implemented. I just need to add @plugin.router() entries for most of what is in vrtplayer.py and add my own for the refresh-part. (Trying to combine refresh with the existing logic is way to invasive, so I am not going to try that with the new scheme).

I think i fixed it. Don't overcomplicate things.

[dagwieers]

Well, I don't like the fact that we have an interface now for removing arbitrary files.
So let's merge this and then see how we can improve things.

[dagwieers]

And thanks for fixing this. The quick succession of changes really speeds up development.

[mediaminister]

Thanks for merging, now we can move forward with the new interface.
The cache refresh could surely be improved. For instance the container refresh doesn't refresh the tvguide caching file.

@mediaminister I am rewriting using the routing module now and it is even looking more fabulous :-)
Hope I can test this in an hour and share it here.
