Title: Time tracker icons not displaying in IE8 and down

I figured out this is because the background color for these icons was declared in RGBA format, which IE8 and dow do not support, and so they ignore the entire background style rule.

The rgba(0,0,0,0.5) equates to #777, and there's really no need to use RGBA here.
