* Avoid remapping jars every time Loom starts
* Attempt to find installer JSON if it isn't found
Remapping Fabric-Loader used to find it every time, now we might skip that we have to go looking for it
* Log a little more when skipping things
Makes it more clear cut when it is avoiding doing things compared to failing after trying
* Enhance support for file dependencies
There's a reasonable chance this might work now, at least more than it did before
* Encourage Gradle to search better
Now it will find both remapped maveny and file dependencies
* Remove some very quiet boxing
Didn't think javac is capable of noticing that
