Adding test for no files found
Merge branch 'master' of https://github.com/dart-lang/chromedeveditor into umop-preferences-editorconfig-parse-simple
Setup contexts for file and container to minimize the repeated passes on parsing and matching.  Moved the initialization into a whenReady Future.
Fixed 2 Glob bugs (incorrect end count causing missing slashes from regexes, and wrong matcher class for char-range pattern). Restored and fixed tests to use contexts.
RegExp optimizations
Lightened up the parser to not care about ints (just floors the value)
Using static convenience method rather than whenReady.  Removed editor_config from spark.dart for now.
