This is a simple extension to tweak the new Core Theme in FG version 4.5.1

The following changes have been made (please refer to screenshots):

• Combat tracker entries have been colored to match the specific entry type.
• Combat tracker graphics have been altered so that the colored entries fit better with the theme.
• Chat window brightness has been toned down to a more gray than bright white and a texture was added.
• All other windows have been toned down to a more gray than bright white color to make the contrast easier on the eyes over long session durations.
