Alter Alert Boxes

[Jeremy Hopkins]

There are some changes we need to make to alert boxes:

1. The ability to insert hyperlinks for "read more" in announcements. Current use of strip tags prevents this
2. Basic style / text decoration on hyperlinks to make them more visible
3. The icons are large and do not align vertically with the text
