Add minimatch patterns to ignoredFiles;

With this commit it's possible to ignore files by glob pattern.

Ex.:
```coffeescript
    esteWatch:
      options:
        dirs: ['./', './**']
        ignoredFiles: ['*~', '*.swp', '*.tmp']
        livereload:
          enabled: false
      '*': (filepath) ->
        return ['rsync:venus']
```
