Security issue: GUI file access, protected config values, and mods

As discussed on IRC.

We have protected config entries that can't be used by JS, such as However, the gui can just `Engine.ReadFile('config/user.cfg') and get that data anyways.

Further, WriteJSONFile can overwrite any file.

These all seem like problems, particularly since we do prevent some access in the simulation ReadJSONFile for example.

Restrict access for Read/WriteFile functions

For security reasons planing to restrict access for ReadFile, ReadFileLines, WriteJSONFile, ReadJSONFile, ListDirectoryFiles, FileExists to the following folders/files:

"gui, simulation, maps, campaigns, saves/campaigns, config/matchsettings.json, config/"
adding "moddata" if some mods need to access and ship custom files that don't fit into other locations mentioned above
