Plugin picks up all files in the source/test folders

[lkonstantinov]

I know the intention is to pick up only *.clj and *.cljc, but this code in NamespaceDiscovery.java:

    scanner.addSourceMapping(new SuffixMapping(".clj", new HashSet(Arrays.asList(".clj", "__init.class"))));
    scanner.addSourceMapping(new SuffixMapping(".cljc", new HashSet(Arrays.asList(".cljc", "__init.class"))));

only affects the StaleSourceScanner implementation. The SimpleSourceInclusionScanner needs to have the inclusion/exclusion collections initialized on construction - so, something like this:

  protected SourceInclusionScanner getSourceInclusionScanner(boolean includeStale) {
    return includeStale ? new SimpleSourceInclusionScanner(Sets.newHashSet("**/*.clj", "**/*.cljc"),
                                                           Collections.EMPTY_SET) : new StaleSourceScanner(1024);
  }

Without the fix the plugin is trying to compile any files it finds in the source directories (.cljs in my case) failing the whole build.
