fix(ngList): use custom separators for re-joining list items

The separator string used to split the view value into a list for the model
value is now used to join the list items back together again for the view value.

BREAKING CHANGE:

The `ngList` directive no longer supports splitting the view value
via a regular expression. We need to be able to re-join list items back
together and doing this when you can split with regular expressions can
lead to inconsistent behaviour and would be much more complex to support.

If your application relies upon ngList splitting with a regular expression
then you should either try to convert the separator to a simple string or
you can implement your own version of this directive for you application.

feat(ngList): use ngTrim to manage whitespace handling when splitting

With the removal of regular expression support `ngList` no longer supported
splitting on newlines (and other pure whitespace splitters).

This change allows the application developer to specify whether whitespace
should be respected or trimmed by using the `ngTrim` attribute. This also
makes `ngList` consistent with the standard use of `ngTrim` in input directives
in general.

fix(ngSwitch): use the correct transclusion scope

If an ngSwitchWhen or ngSwitchDefault directive is on an element that also
contains a transclusion directive (such as ngRepeat) the new scope should
be the one provided by the bound transclusion function.

Previously we were incorrectly creating a simple child of the main ngSwitch
scope.

BREAKING CHANGE:
** Directive Priority Changed ** - this commit changes the priority
of `ngSwitchWhen` and `ngSwitchDefault` from 800 to 1200.  This makes their
priority higher than `ngRepeat`, which allows items to be repeated on
the switch case element reliably.

In general your directives should have a lower priority than these directives
if you want them to exist inside the case elements. If you relied on the
priority of these directives then you should check that your code still
operates correctly.
