Promote the Plugin Controller source file to Objective-C++, and add a
simple data cache that holds on to requests for up to 5 seconds after
their last access, for preventing spammed requests from hitting files
over and over. This is apparently really relevant to the CUESheet reader
and its embedded CUESheet handling, as that tends to reread the same
file over and over as it populates the playlist with tracks. The nested
reader can also lead to repeated reading even on files without CUESheets
embedded.

Artwork deduplication should be done with hashes, not by full data
comparison. This should be a lot faster loading artwork from files now,
especially if the playlist already contains a lot of unique artwork.

Significantly reduce the memory footprint of adding tracks to the
playlist, by coalescing the NSString and NSData objects in the info
dictionaries as they are being loaded in the background, into a common
data set which will then be discarded when the whole job is completed.
