DIRECTIVE_PATTERN matching too much

[ameboide]

The regexp that matches directives is too generic, which results in actual lines of code being stripped. For example, it breaks the marionette framework by stripping the 3rd line in the stripDirectives task:

      hash[v.replace(pattern, function(r) {
        return ui[r.slice(4)];
      })] = hash[v];

For the moment, I think a good idea is to use the file as a "manifest" (don't put code inside), it's a valid option right now.
