Extended Filenames v1.0.0.0

This is just a little mod I wrote to allow the use of $mapdir$, $moddir$, and $FS22_SomeModName$ inside of more configuration xml files than the vanilla game allows.
Once again, this was written based on a request. The idea was to allow mods to dynamically load files from other mods via xml configuration (like vehicle and placeable xml files).

The format goes as follows:
$mapdir$path/to/filename.xml uses the current map mod folder
$moddir$path/to/filename.xml uses the current mods folder
$FS22_SomeModName$path/to/filename.xml uses a specific mod folder
