SoundCloud and InTheaters fixes.

SoundCloud:
- Added a limit to the number of characters allowed for the sound's title.
- The list now occupies the whole ZCI box when the image is set to "hide."
- The plug-in now loads a larger image.
- Added a div at the end to push the favicon down.

InTheaters:
- Now shows either "Opening Movies" or "Currently in Theaters" depending on the query.
- Added back a helper function called "list" that guarantees that we only show five items.
- Like the SoundCloud plugin, the list now occupies the whole ZCI box when the image is set to "hide."
