allow external js files as parameters

[pk-fr]

// needed js files
var js = {
ace : "//cdn.jsdelivr.net/ace/1.1.3/noconflict/ace.js",
aceExtWhitespace : "//cdn.jsdelivr.net/ace/1.1.3/noconflict/ext-whitespace.js",
pbSyntaxHighlighter: CKEDITOR.plugins.getPath('pbckcode') + "dialogs/PBSyntaxHighlighter.js"
};

for locally configured ace, ( with no internet acces by example), it would be usefull
to configure those scripts location as parameters
(ie. sth like : config.pbckcode.ace = "/my_path_to_scripts/ace/ace.js" )

thanx
