Minor improvements to announcements

Summary

Minor improvements to the new announcements feature

Problem Definition

Feedback has been great, just want to incorporate it.

Proposal

• Remove extra "X" from the main content holder for announcements. Only use "X" in the datacards
• Change icon to megaphone or bell (bell is more common)
• Add hover to menu icons (announcements and login)

Regarding the X - How often do we expect announcements to happen? If there's a bunch I think it would be annoying to have to manage each one, maybe on the main content holder there could be a clear all announcements text or something if there is >1 announcement? An alternate clear would avoid the potentially odd double X too. Just a thought!

@ahatzz11 I just changed it to have a "Close All" button, no matter how many announcements there are. I think it looks fine and makes sense at this stage.
