Add abillity to mark additional directories as excluded

[ApexModder]

Title says it all, add the ability to mark additional directories as excluded

Mostly helpful for directories like the ./run config, excluding this will stop searches & refactors from trying to find / modify in logs and config files

Also additionally, auto-detect & ignore directories set in any run configurations

Example way to mark excluded directories in the workspace() { } block

workspace(Intellij) {
	excludeDir path('./run')
	excludeDir './run' // auto convert to `path()` object, for QoL?
}
