Update FileSystem.cpp

defaulted fs_resourceLoadPriority to 0 so it is easier to develop with the engine

does this mean that specified path will be prioritised instead of normal lookup. Normal lookup meaning first in base/ then in mod path?

In that case I am against this because base/ should contain only stuff that will be extended in mods, not something that will be used only in case nothing else is there.

We should fix base instead.

If I understood correctly in the idtechforums, this is only relevant if the assets are in .resources files, right?
This is currently not the case for OTE and possibly never will be (I wanna bring back .pk4).

However, I haven't looked up what this option really does, if the descrption("if 1, open requests will be honored from resource files first; if 0, the resource files are checked after normal search paths") is right defaulting to 0 indeed makes sense when not using resource files.

yes this is only for the resources,

in OTE makes not sense to keep this at 1 unless we end up building resources, but then it's up to us to bring it back to 1, I don't think we will ever really use the resources, but the option should remain there. so only changing it to 0 we keep it there but it doesn't interfere with the development of OTE.
