Probably plenty of missing spots but I think it's okay for now. Let me know on SB if you find something you think needs changing.

v.2.1 - Changed the quick reply threadmark input background.
v2.0.1 - A few more tweaks with the Threadmarks.
v2.0.0 - Fixed the Threadmarks after their recent update.
v1.8 - Made the New Message(s) notice legible.
v1.7 - Changed quote header color so the original post link shows.
v1.6 - I'm sure I'm using versioning wrong, cleaned up tab/spacing.
v1.5 - Organized a bit more by changing all colors to HTML code.
v1.4 - Added comments and organized the code a bit.
v1.3 - The arrows on the quotes are still there, but I can't figure out how to change them from blue without changing all the other posted links.
v1.2 - Recolored nav stuff.
v1.1 - Fixed lists and some other stuff.
