- Set package to performance for the module.

Added .htaccess information for also redirecting with clean urls disabled (still, mod_rewrite is required!).

removed configurable features. Benchmarks did not show any significany difference with/without features.

Changed admin paths and menu type in order to appear on the configuration page (this was not the case as .../performance is no main administration menu level).

Applied Drupal CS and fixed download path and content type (otherwise some browsers would assume HTML content and set an .html file extension).

Rewrite of how module is administered. Added configuration page and the features of the module are now configurable. .htaccess configuration is also handled via the configuration page.
