[scriptdocs] Path references are incorrect

@daid via Discord:

Audio can be in /scripts/audio/ as well. Nothing is special about /resources/ or scripts, both paths get searched.

Yes, resources, then scripts then packs. The order in which resource providers get build in main.cpp

Remove or correct scripting docs references to specific paths that suggest either resources/ or scripts/, which are incorrect.

Document the full traversal order in the wiki for reference:

if mod=something, then ~/.emptyepsilon/resources/mods first if $HOME is defined, then packs in ~/.emptyepsilon/resources/mods, then resources/mods, then packs in resources/mods, then resources/, then scripts/, then packs/, then if $HOME is defined then ~/.emptyepsilon/resources, then ~/.emptyepsilon/scripts, then packs in ~/.emptyepsilon/packs, and then if there's a RESOURCE_BASE_DIR defined then resources and scripts and packs in there

then EE checks that same list, in the same order, for a corresponding locale subdirectory for the main .po files

Search the scripting documentation for references that imply resources/ or scripts/ are special, then compare them with the traversal order described in the issue. Correct those references and document the full traversal order, including locale lookup, in the wiki; the work is done when both the scripting docs and wiki match the stated order.
