enable schema caching by default and clear it during migrations
use mptre/php-xspf from upstream (fixes #198)
don't force HTTP when importing font in bootswatch.less (fixes #197)
factor out image URL determination to Thumbnail::getOriginalUrl()
fix missing line breaks when formatting logged exceptions
remove MediaNotFoundException and use PageNotFoundException instead
log the error data contained in JSON-RPC exceptions (fixes #193)
reduce variable scope slightly
make application name an optional setting
factor out the header part of the layout to a separate file, and only
render the application name if it's been defined
remove media query hacks for the actor grid, this way they'll scale
better. Also use a larger thumbnail size.
don't render the cast if there is nothing to display (can happen for
really obscure movies or foreign TV shows)
render the actor grid the same way for both movies and TV shows. This
means that clicking an actor image for a TV show takes you to the
movie search page, which arguably makes more sense than trying to find
another TV show with the same person.
change default padding for "well" containers
make the layout adapt to larger screens by using a fluid container
(fixes #203)

Some hacks are needed to force the container to align with the result
grid, hence the extra LESS files.
