project renamed, switched focus to the create element function

- Powerhouse is now power.js
- All functions but create_element have been depracated. This function
now is named power, it is superior to any of its previous versions, it
allows not only creating elements based on tag names (div, span, p, a,
etc), but also sets element attributes (class, id, style, placeholder,
href, etc), and latest of all it supports inline javascript event
handlers (onclick, onkeydown, mouseover, etc)
