508 Compliance Report -- 1st Pass

Description of problem:  508 Compliance, Subpart B § 1194.22.
 A text equivalent for every non-text element shall be provided (e.g., via
"alt", "LongDesc", or in element content).

Non-text elements and graphics used to convey functionality and/or
information to the user must be accompanied by an appropriate alt or
longdesc attribute containing a meaningful description of the element
and/or its purpose.

The element description should focus on the purpose of the element and
not the appearance of the element itself.

Where an image is used for appearance of design-related purposes only
(in the case of padding or positioning), such images should be labeled
with a blank alt attribute.

Why this is important.
People using a screen reader, or other user agents such as a text based
console, need to have meaningful alternative text assigned to non-text
elements so that they can distinguish between important functional
elements and visual elements that are simply contributing to the
appearance of the page.

Specific instances of non-compliance:
1) login image
2) images in tree view
3) images on tab folders 
4) images used for favorites
5) images used
