* When looking for texts inside the page or inside
other containers we should wait until the elements
are visible.
* Same when expanding tree nodes.
* Normalizing loops to spin() function using
behat_base::TIMEOUT and behat_base::EXTENDED_TIMEOUT,
leaving TIMEOUT for DOM load processes and
EXTENDED_TIMEOUT for long processes that involves JS
too.
* Add page load waits between actions that involves
reloading the page.
In general aiming for compatibility with multiple browsers,
firefox, chrome and phantomjs to be more specific.
* Removing hardcoded waits
* Adding @_alert, @_switch_window and @_switch_frame tags,
to label actions that different drivers have problems with.
* Adding missing @_files_upload and @_only_local tags to features that
uploads files.
* Fixing a few wait for page ready what specified miliseconds.
* New methods to ensure elements (usual selectors), sections and editors
are ready to interact with
* Changing the select an option implementation to deal with the different
drivers implementations when listening to JS events.
Nasty strings includes html entities and
non-breaking spaces followed by spaces which makes
very hard to find these strings in the DOM html,
this patch keeps the non-breaking spaces and all
the nasty characters, but leaves them isolated from
other regular spaces. It swaps the strings to HTML before
finding elements in the HTML that matches that contents.
