* show human readable value for default values

* update screenshots

This is actually better this way instead of assigning $

* Add possibility to select a specific frame within a page

eg `page.selectFrame('myFrameName');` and at the end of the test `page.selectMainFrame();`

What doesn't seem to work yet correctly is typing within the frame. I presume the position where the click should happen is not calculated correctly (it clicks before sending keys).

* get correct position within frame so .click works

* when selecting a frame within a frame, do not calculate position again

* fix an issue where $ might not be defined but window.jquery

* post JS events when a user performs an action

* post events for website

* also post the measurable type

* Post current action in Template.beforeContent event

Be good to have this as well when wanting to restrict content to certain actions

* for consistency also add event to dashboard

* New event that lets plugins trigger notifications in the admin area

They have to be triggered before assigning the notifications to the view and there is no other way to determine when a plugin is supposed to trigger notifications in the admin. Ideally, in the future we would even move the notifications above to CoreAdminHome or somewhere else eventually.

First thought of using `Controller.addAdminNotifications` as we often use this wording but then we would need to rather do `Piwik::postEvent('Controller.triggerAdminNotifications', &$notifications);` as otherwise nothing can be added.

Plugins could actually also use this event to cancel notifications where in the past it was needed to hide them via CSS. 

Happy about any other naming suggestions but want to keep it "specific" to notifications and not something to general like `postEvent('Controller.renderAdminView, $view')`.

* document new event

See http://us2.php.net/manual/en/function.random-int.php : random_int — Generates cryptographically secure pseudo-random integers

* updates changelog

* updates expected screenshot

* improve message

* Add system check for the hash() function

* Update expected screenshot for hash() system check

If nobody has a problem with it, can also add this option by default as there should be no problem with it.

* set ignore ssl error by default
