Scriptloading overhaul (#163)

* - Added option to RunConfig.cs for mods to compile with non-publicized assemblies.
- Added default values attrib to RunConfig.cs
- Added thread sleeping to CsPackageManager.Dispose() to give time before generating a strong-ref to check acl unload status.

* - Added PrintWarning to ModUtils.cs
- Made previously unloaded ACLs warning only.
- Made plugins unload after lua script disposal.
- Small code cleanups.
- Cleared acl record references on unloading.
- Made ACL unload run via event hook.

* Made non-pub asm compilation name the same long-a** name in XML, as per Evil's request.
