Added support for "page.click()" and "page.loadJsFile()".

* click() accepts a "querySelectorAll" input - can click on multiple things in one call
* loadJsFile() is synchronous at loading JS in the page
* added 2 examples in JavaScript to show how to use (and test) the new methods
* NOTE: someone will have to generate the .coffee version - I tried using "http://ricostacruz.com/js2coffee/" but it hangs and I'm not willing to learn why :P - I don't like Coffee Script.
"loadJsFile()" -> "injectJs"

* According to Issue #32 (http://code.google.com/p/phantomjs/issues/detail?id=32) I added a "lookup logic" that searchs for the file following those steps:
*# Search for file at given path (relative to PWD or absolute - no difference)
*# Is file there? Inject it
*# Is file not there? Try looking for it in "scriptLookupDir"
*# Is file there? Inject it
*# Is file not there? abort
* "scriptLookupDir" is an extra property for WebPage, that, as by it's name, defines a place where to look to script to inject
* Script can alter the scriptLookupDir, if they want
* Updated "injectme.js" accordingly
Renaming "page.handlers" to "page._handlers": more common for "private" stuff.
Merge remote-tracking branch 'upstream/master' into utilities
Merge branch 'utilities' of https://github.com/detro/phantomjs into utilities
Added "includeJs()" to "page".

* It includes a script in the page
* It uses a callback to ensure any code dependent on the include runs afterwards
* It uses the signal "javaScriptAlertSent" to do the trick (is there another way to be notified of the "onLoad" event from outside the page context?)
* It uses a "private" slot "_appendScriptElement" to pass the script url in the page context (is there a better way?)
Normalie user-provided script path
More work on "injectJs"

* "injectJs()" now supports ".coffee" input
* "injectJs()" is now available for the "phantom" object as well
* CSConverter is now a singleton embedded in the Utils static class
* The code used by "injectJs()" is now centralised in the Utils static class
Removing "page.click()" for now.

There is need for a discussion to decide how to do this.
