Support resolveLoader.alias

I'm trying to change a resolver for a test. Specifically, I have a file being required via "worker-loader?inline=true!pdfjs-dist/build/pdf\.worker", and I would like my test suite to treat it as "raw-loader!pdfjs-dist/build/pdf\.worker".

I tried to abuse the current setup like so:

resolve: {
  alias: {
    "worker-loader\\?inline=true!pdfjs-dist/build/pdf\\.worker": path.resolve(__dirname, "node_modules/pdfjs-dist/build/pdf.worker.js")
  }
}

Unfortunately, that simply prefixes the import with "./", changing it into "./worker-loader?inline=true!pdfjs-dist/build/pdf\.worker".

Also a minor thing, but if a filename has a "." in it, your regexp match will treat that as any character instead of a period.
