Redesign file system/resource system

[MrSapps]

Current system is quite awkward because all games data is thrown into one big blob which can make picking the correct file tricky.

Need a system that:

• [x] Has a list of known data stores such as AoPc, AoPsx, AoDemoPc, AoDemoPsx etc.
• [x] Some big database of files to which LVL's the live in, this so CD1/CD2 files are picked correctly.
• [x] A way to have separate configuration of "mods" that can override any file, including a file, or file chunk/animation frame within a LVL. A mod will have to specify which data stores it depends on. Or this could be figured out automagically since we'll have the data base of files.
• [x] A mod should be able to include another mod for "layering" for example if someone has a custom path and someone else has a HD mod, then it should be possible to layer the HD mod on top of the new path.
• [x] Perhaps a higher level way of mapping resources, for example to give each animation a named ID and allow overriding in this way too. For example "kAbeWalkLeft" where overriding means something like providing a PNG with this name, otherwise the correct BND file, chunk and animation set is looked up.
• [ ] Overriding should support new file types, for example overriding a camera should ignore the file extension in the comparison and then use the extension to select the correct loader. so if the real game had foo.cam and you had a remade version, then it should be possible to set an override of foo.cam to foo.png
• [ ] Do some basic first run search for the game data, check steam location, registry keys etc.

Generating the file DB is possible to do via a tool, including generating the resource ID tables, there would then be a manual step of name the known animations and map AO to AE animations ids if they are not the same (not yet checked).
