Prepend scripts in layout

When view scripts append scripts based on jQuery, they are registered last
so jQuery is already loaded.
Add inlineScript() helper

For faster DOM parsing it is recommended to place some scripts just above
the </body> tag. Rendering the inlineScript() helper here makes it possible
to inject files in both the <head> and at the end of the <body>
Use long tags with echo statement
