cleaning code and small optimizations
Refactor Infinite Scroll init. Optimizations.  Code cleaning.
Everything is loaded dynamically without extra requests directly inside before_body_end.
jQuery is loaded conditionally only if it doesn't exist
jQuery is loaded from the CDN first it doesn't exist and it has a fallback to the local file
Hide toolbar using js instead of changing the template from the layout
New options for hiding only the pagination, new selectors for the toolbar and pagination
Removing deprecated code
load jQuery from CDN with fallback to local. New system config for choosing if jQuery should be loaded by InfiniteScroll or not
added better support for jQuery. It should work even if jQuery is loaded after the initialization script is declared. For example if someone is including jQuery after before_body_end block
reduce setTimeout timer used to check when jQuery is available
disable Memory (and hence cache)
Merge pull request #53 from enriquepiatti/load_all_js_in_one_block
