The idea here is to completely merge the resource management into the file system so that Blood's DICTNODE is merely an alias to the internal FResourceLump.
A two-tiered resource system is not something I consider worthwile, it made sense to get around Builds crappy cache but in the long term this is not a good solution for a multi-game port to have a resource management system in the backend and another one put over it in the front end, both with their own caching logic that might interfere with each other. Better merge it into one that can handle everything.
This is a lot of changes in a lot of code because nothing here was abstracted into the sound system. :(
Hopefully most of the affected code here can be tossed out soon, it's not pretty.
