Added 'cssFilesInsertBefore' parameter

[alonl]

Added an option to provide 'cssFilesInsertBefore', for inserting css files before a specific element.

Don't define cssFilesInsertBefore as a global config option, use the params instead so that it can be defined as a "when you need it". Params can be defined in a module config object like this:

$ocLazyLoad.load({
    name: 'mgcrea.ngStrap',
    insertBefore: "#myId",
    files: [
        'bower_components/angular-strap/dist/angular-strap.js',
        'bower_components/angular-strap/dist/angular-strap.tpl.js'
    ]
});

or as an option config object (defined for all modules lazy loaded with this function when used as the second parameter):

$ocLazyLoad.load(
  [{ name: 'mgcrea.ngStrap', files: [ ... ] }, { .... }],
  { insertBefore: "div .myClass" }
);

It would take a css selector. If you define a css selector that returns multiple elements, it will only take the first one into account (use querySelectorAll).

Maybe that you could define multiple choices, like insertBefore, insertAfter, appendTo. It should affect cssLoader & jsLoader if you use it in the buildElement function (not sure if it would really be of any use for the jsLoader function though).

Also you should edit the README.md to add this new param and explain how it works. Add a note about browser support of querySelectorAll (in IE8 it only works with css2 selectors)

Done. Hope that's fine.

Almost, just change:

var insertBeforeElem = angular.element(params.insertBefore) || anchor.lastChild;

to

var insertBeforeElem = anchor.lastChild;
if(params.insertBefore) {
  var element = angular.element(params.insertBefore);
  if(element && element.length > 0) {
    insertBeforeElem = element[0];
  }
}

We don't want to do a DOM query every time for nothing (moreover when you know that this param will rarely be used).
I'll you test it to make sure that it works :)

[alonl]

Got it. I've tested it of course. :)
