Added redirectPluginFiles action

[NiLSPACE]

redirectPluginFiles is an action similar to redirect which allows you to redirect paths to another path. redirectPluginFiles only looks at files inside the plugin's folder.

Also fixed bug where the simulator would check the inheritance of strings and functions.

The following has been added to the ScenarioFiles.md file:

redirectPluginFiles

Adds a redirection for files inside the plugin folder. All Cuberite APIs that take a file or folder path check if the file needs to be redirected. This is useful if you want to use a different configuration file in your scenario. It can also be used to insert mocks in the code. The following table should make it clear how it works.

Key provided in dictionary	Value provided in dictionary	Path provided by plugin	Path actually used
config.cfg	config.cfg	Plugins/[myplugin]/config.cfg	[scenarioPath]/config.cfg
Classes/Storage.lua	mocks/Storage.lua	Plugins/[myplugin]/Classes/Storage.lua	[scenarioPath]/mocks/Storage.lua

Takes a dictionary table which maps the old paths to the new paths.

redirectPluginFiles
{
    -- Redirect the 'config.cfg' file from the plugin folder to the scenario folder
    ["config.cfg"] = "config.cfg"
}

If there are no objections I'd like to merge this.
