Code raises Exceptions instead of its subclasses

[Tomin1]

The code always raises Exception instead of one of its subclasses. That is not very good idea because it makes writing good unit tests hard. I fixed one more error with the unit tests on commit a163e92 that was not caught by the nosetests because the test expected any error (and got TypeError in this case). Assigning proper (or even custom) Exception subclasses would make the testing a lot more solid.

It's always a sin to use "bare" Exception. At least as bad as excepting one ;)
You are more than welcome to fix this informality.

Thanks. I'll look into that when I have some spare time.

Btw. I could not play videos with Kodi plugin. I think Elisa made some changes to the way videos are downloaded. But that's another issue and maybe not even on this repository.

I did the simples thing to do and created a very simple custom exception because there isn't really any Python Built-in exception that fits. I think there are still a some things that I might change like expecting Exception in elisaviihde.py code. The work I've done is in branch Tomin1:new_exceptions (especially commit ff4c636) and I'd like to hear any comments on that.
