James D. Callahan III:
    - Only update chat frames which are shown or docked.
    - Removed some dead code.
    - Fixed some global namespace pollution.
    - Re-worked tab highlight toggling to actually make sense and not kill resources.
    - Disallow un-docked frames from flashing.
    - Don't lower the alpha level of flashing frames.
    - Set the tab name color for un-docked frames to the active tab color.
    - Finalize AddOn name-change in the ToC. SavedVariables will be lost.
    - Add "Classic" to the localization.
    - In UpdateChatFrames() - Assign TAB_DATA[index] to the "cache" variable.
    - Until I figure out something nifty to do with the 3.3.5 TabGlow texture, hide it.
    - Fixed references to (hopefully) nil global variables.
    - Added the 3.3.5 "NewMessage" texture as an alert texture option.
    - Cleaned up GetTabColors()
    - Renamed TabAlerts.lua/toc to ChatAlerts.lua/toc
    - Removed some debug prints.
