Bug 923577 - Ensure that we remove icons of hidden roles r=crdlc

When installing an application that is hidden, we have to make sure,
when updating the icon, that we remove it. This case happens especially
with packaged role system app, like, in this bug, a ringtones app. We
end up creating a temp icon (because we only have a updateManifest at
that time and cannot decide the role of the app) while downloading,
which is not removed once the app is finally installed.
bug 925970

* Get rid of slight shift from placeholder e.me elements and actual when in use.
* Specify font-family to use, this is unfortunately a must as we do not map our light font versions to CSS standard names.
* Degrade to older known fonts to support devices from partners that use incorrect fonts (and there are many).

Bug 912010 - [Keyboard][V1.2] Default Keyboard when all keyboards are de-selected - r=rlu r=garychen r=arthurcc

- Refactors `KeyboardHelper`
  - Renames the application method to `getApps`, which now caches response until the apps change
  - Adds a new API `getLayouts` to get a callback with an array of layouts.
  - Adds a new API `watchLayouts` to get a callback whenever layout settings or apps change
  - No longer calls `saveToSettings` itself when changing layout parameters.  This allows a consumer to batch operations before saving.
  - New method `checkDefaults` will make sure there is at least one `text` `url` and `number` keyboard enabled, calling the callback with anything it enabled.
  - +unit test suite.

- ManifestHelper now automatically returns a ManifestHelper for each object it contains
  - +unit test suite
  - now waits until access time to handle the language selection instead of creation time
     - this allows holding the one manifest helper and having its "name" property change with the language

- Settings Changes
  - Now uses `watchLayouts` from keyboard_helper
  - Now calls `checkDefaults` when disabling a keyboard
    - If a default is enabled opens a DefaultKeyboardEnabledDialog
  - Removed a bunch of commented out code for dealing with the old layout settings

- System Changes
  - Now uses `watchLayouts` from keyboard_helper
  - Will call `checkDefaults` whenever it can't find a keyboard to show, showing the default from `text` if it still can't find one

- Test suite
  - Moved some mocks to shared and updated require statements
  - Mock Settings now allows a "sync mode" that can call the callbacks for observers on demand.
