Optional htaccess creation

I recently ran into the issue of "Certain hosts do not like multiple .htaccess files". The css_gzip module gets around this by providing an option to disable the creation of the htaccess file and then provides what you need to add to your main drupal htaccess in the README file. The attached patch implements this exact feature into javascript_aggregator. Its a multiple file patch for javascript_aggregator.module and README.

With this feature, you can now have gzipped CSS and gzipped JS on these restrictive hosts.
