Feature security exceptions

refs #25

Added an alert function to the ozpIwc.utils. This is temporarily tied off to console.log, but should be tied to the angular/bootstrap modals used in #38.

Alerts in place for the following scenarios:
* Firefox localStorage disabled (about:config -> dom.storage.enabled = false) will return an error message "localStorage is null"
* Firefox/chrome return a dom error code `18` (Security error) when writing to local storage is not allowed due to privacy settings (cookies disabled)

Follow-up:
* The alert should notify the user of the `message` regarding the exception if it can not be mitigated.
* The alert should have an expandable display to display the error object (like a "see more details").
* The alert should have a checkbox for "don't show this message again" which should store its reference of not showing in the data.api
