v3: improper params escaping

[archseer]

Had a song titled "10 - Haj F. Karimah - Consequences". It got displayed correctly in the search page, and the link pointing to it's song was of the format artists/Various Artists/songs/10 - Haj F. Karimah - Consequences. I got an error:

as you can see, the params got improperly parsed, the title got split at the dot, and the remainder got put into the format key.

{"artist_name"=>"Various Artists",
 "title"=>"10 - Haj F",
 "format"=>" Karimah - Consequences"}

There seem to be further problems with the dot, the album name is properly displayed in the search page ("DreamTime Departures Vol. 9")

...but in the /:artist/albums/:album page, again, everything to the right of the dot is missing.

Apparently this can be easily solved with constraints: http://legacy.x3ro.de/rails-3-routing-parameters-dots/
