[haXe] [js] being sure all is loaded before proecessing

Mon Apr 3 21:58:47 CEST 2006

No, because you can't be always sure that the DOM tree is built before the
Main method is processed. If your js is small enough and in cache it should
be theoretically parsed before the </body> starts the parsing of the DOM.
This also prevents problems in case you want to include other JS files (or
CSS) which maybe complete their loading after the main method has been
fired.
Another good reason is to put the <script> tag in the <head>, which is in my
opinion the right place.
