A lot of the visuals in the dashboard have been around for a very, very

long time. In particular, the "new updates" and "Ship It" indicators

have been there since Review Board 1.0, and really aren't ideal

representations these days. The "New Updates" used a chat-like icon,

which was fine when it was originally made for indicating new reviews,

but it also indicates review request updates. The checkmarks for Ship It

(used on both the Ship It icons and the "My Comments" icons) don't

really scream "approval" so much as "thing done," which duplicates the

visual language used for fixed issues.
There were also a couple of other things I've been wanting to alter. The

counts on the sidebar were a reddish color, which some have taken as

"something wrong" or "something needing my immediate attention." The "!"

for issues was rendered as text, which differed between browsers/systems

a bit and wasn't the nicest-looking exclamation mark. The text on the

issue and Ship It indicators didn't align. The Ship It indicators also

used background images instead of gradients, which didn't look as nice

when loading the page.
This change fixes all these issues, improving the overall look of the

page and making it a bit more fresh-looking.


The colors on the sidebar now have a bluish color, blending in better

  with other aspects of the page.


The "New Updates" now uses a blue dot, which is a common visual for

  new things on phones and other webapps.


Instead of checkmarks for Ship It, we now have a "thumbs up" visual,

  better indicating approval.


The exclamation mark for issues is now an icon, carefully designed to

  stand out clearly on all displays.


The column header, column name, and alt text for the Ship It/Open

  Issue column no longer claims to just be about Ship Its, factoring

  issues into the naming and column icon.


The icon width/height for the Ship It and Open Issue indicators are

  now the same size, and the text all aligns.

Tested all changes on Retina and non-Retina displays.
