BREAKING CHANGES:
The Option component’s `checked` attribute has been renamed to
`selected` in order to select an option. This is to the follow the MDN
spec for a select option:
https://developer.mozilla.org/en-US/docs/Web/HTML/Element/option
If a `ngModel` is added to the Select component the value of the
`ngModel` will take precedence over the `selected` attribute.

refactored the sass naming to use `text-capitalization` instead of
`text-transform` since it now has an actual `transform` property and I
think this will be less confusing than having a `text-text-transform`
and a `text-transform`.

Update tabs to reflect the material design bottom navigation spec:

igation-usage
BREAKING CHANGES:
Material design mode defaults have changed to the following:
```
tabsHighlight: false,
tabsPlacement: 'bottom',
tabsHideOnSubPages: false
```
`tabsHighlight` can now be passed as an attribute on the `ion-tabs`
element, this allows for tabs to be added in multiple places inside of
an app and enable the highlight on some of them.

Use NavController as the public API, and NavControllerBase as the
internal API. Refactored all app/nav/tabs unit tests and created
centralized mocking functions.
The input highlight can now be enabled for ios. Fixed wp’s
valid/invalid highlighting. The highlight bar now goes on top of the
item-inner border so it will resize if there is an icon to the left.
BREAKING CHANGES:
Fixed typos in the input highlight variables:
- `$text-input-md-hightlight-color-valid` ->
`$text-input-md-highlight-color-valid`
- `$text-input-wp-hightlight-color-valid` ->
`$text-input-wp-highlight-color-valid`
Modified variables to turn on/off the highlight:
ios (defaults to false for all):
```
$text-input-ios-show-focus-highlight: false !default;
$text-input-ios-show-valid-highlight:
$text-input-ios-show-focus-highlight !default;
$text-input-ios-show-invalid-highlight:
$text-input-ios-show-focus-highlight !default;
```
md (defaults to true for all):
```
$text-input-md-show-focus-highlight: true !default;
$text-input-md-show-valid-highlight:
$text-input-md-show-focus-highlight !default;
$text-input-md-show-invalid-highlight:
$text-input-md-show-focus-highlight !default;
```
wp (defaults to true for all):
```
$text-input-wp-show-focus-highlight: true !default;

$text-input-wp-show-focus-highlight !default;
```
