Added function flx_minRequested() to deal with local CSS and JS minification on the fly
using yui-compressor.

Since Carmina has a flag ( ISLIVE ) that indicates if it is running on a live
server or not, we use that to minify on the fly javascript files and
stylesheets that are loaded to buffers ( see loadScript() and loadStylesheet() ).

Hence, from now on, when pushing a new software release, part of our release cycle will
flush all minified files in order to guarantee that all files are up
to date.

This proved to us to be a more effective approach than trying to keep track
of all css and js files used by the system then run minification scripts
and make sure that all had been regenerated. Another problem with that is
when using the dynamic debugger, live simulation can take place, so when
working on css aspects you have to minify your files prior to executing a page. A
rather annoying way to deal with CSS stuff.

Not covered yet is the situation where a css file imports another one. More to
come on this.
Code adjustment to loadScript() and loadStylesheet() to deal with auto-minification of
JS and CSS files when running or simulating a live environment.
Resource/share have been changed for share
Added a more explicit error message when there is a problem with the Cache file
