Every single step that sets or gets a value from a field
has been updated to follow the same behaviour both when
using it through a single step or through generic steps
like "I fill the moodle form with:", to resume all the
changes:
- Created a behat_form_group to re-guess the field type
  and act appropriately setting and getting it's value
- Normalize all getters and setters to use behat_form_field
  children
- Complete behat_form_checkbox to trigger the appropiate JS
  event needed to perform some JS scripts that are listening
- Refactor MDL-43713 multi-select changes and remove
  the two new steps introduced there as that behaviour can
  be managed from the generic getter
- Added a new step definition to check a capability permission
  as we changed the way radio buttons gets it's value

This patch implements:

1) Normalization of options. Before the patch options
in a select were being returned as "op1 op2 op3" by selenium
and "op1 op2 op3" by goutte. With the patch, those lists
are always returned like "op1, op2, op3". If real commas are
needed when handling multiple selects they should
be escaped with backslash in feature files.

2) Support for selecting multiple options. Before the patch
only one option was selected and a new selection was cleaning the
previous one. With the patch it's possible to pass "op1, op2" in
these steps:
  - I fill the moodle form with (table)
  - I select "OPTION_STRING" from "SELECT_STRING"

3) Ability to match multiple options in this steps. Before the
patch matching of multiple was really random, now every every
passed option ("opt1, opt2") is individually verified. It applies
to these 2 steps:
  - the "ELEMENT" select box should contain "OPTIONS"
  - the "ELEMENT" select box should not contain "OPTIONS"

4) Two new steps able to verify if a form have some options selected or no:
  - the "ELEMENT" select box should contain "OPTIONS" selected
  - the "ELEMENT" select box should contain "OPTIONS" not selected

5) Change get_value from xpath search to Mink's getValue() that is immediate
(does not need form submission) and works for all browsers but Safari, that
fails because of the extra ->click() issued.

Note all the changes 1-4 only affect to multi-select fields. Single
selects should continue working 100% the same.

The change 5) causes Safari to fail. The problem has been traced down to
the extra ->click() present there. Anyway there are not test cases
requiring that "immediate" evaluation right now. Only the special feature
file attached verifies it.

NodeElement->hasAttribute() (JS enabled) queries selenium
about whether it has any attribute or not, if due to an
AJAX request the field node changed selenium can not access
that node and throws an exception.

To select an option is specially painful, every browser
behaves differently and phantomjs just joined the party
throwing "Element does not exist in cache" random
exceptions that we need to catch.

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.

- Escaping steps arguments redirected to other steps
- Adding normalized-space() in all contains() assertions
- General xpaths review
- Convering provided xpath text strings to xpath literals
  to avoid problems with arguments containing both single
  quotes and double quotes

When the elements to interact with are not
available anymore.

Also changing from SeleniumDriver checking
to GoutteDriver as is less probably to change
goutte than to change selenium.

Moving from phpunit test environment
to a specific behat test environment
