fixed missing import for customitemservice, added bundle loading sequence in the program.cs (#333)

* Added missing import for reflection /bonk

* Implemented bundles.json loading directly into program.cs

`IsBundleMod` is now read from all loaded mods metadata, and if set to true the bundles.json is read from the mod directory.

* re-assign the sorted valid mods to the loadedMods list

since ValidateMods returns the sortedLoadedMods, this is the list of mods we should be passing to our other spots
