IC2 Overrides user-selected XSD mapping for metadata

[Xander Victory]

In com.illuminatedcloud.intellij.common.fileType.IlluminatedCloudFileTypeRegistry#registerMetadataXsd you appear to be manually adding XSD mappings, which overrides user-specified mappings saved to the project.

Is there a particular reason for this instead of using com.intellij.standardResource or com.intellij.standardResourceProvider EPs?

Normally this wouldn’t be a problem for users, but I’m augmenting mine a little and want to use it instead.
