Convert rawFolders from String to FolderList
Continuing in the Parcel > String vein, switch rawFolders to use
FolderList, a small immutable Parcelable class. Individual
Folder objects are still stringified when used alone, but those
are not time-sensitive cases (e.g. generating a view intent).
Traceview on Nexus 7 shows 61% speedup in serializing and
deserializing folder rawFolders. Overall time for Conversation
construction appears to go up, but that's because the previously
lazy-deserialization is now done in the constructor. I think
this is okay, since the only performance-sensitive codepath
that constructs Conversation objects is the conversation list,
which always needs rawFolders.
