Allow folders when "Implicit Mutual Exclusion" is used

[Paril]

Currently, this feature seems to have each folder treated as a unique AngelScript module - this probably makes sense if you've got multiple projects in one folder, but I'd like to organize some of my script files into subfolders. Unfortunately, this seems to break the LSP.

Random types (even ones within the same subfolder) are not picked up; for instance I have game\client.as and game\edict.as, but ASClient declared in client.as seemingly cannot be seen in edict.as. It should be easy to reproduce with this setup;

• Have "Implicit Mutual Inclusion" enabled
• Make two subfolders in project root
• Make a.as in one folder, and b.as in the second folder
• Create a type in a.as
• Attempt to use the type in b.as
