Next time please put this into Modded Client Support as a Crash Report is not a Mod.
I also advise you to look up your crash reports before posting as someone may have already had your problem before. I did find a thread where someone did have the same error as you.
Also, please try to make your Crash Report a bit more organized next time. It's a bit hard to read.
Anyway, for the fix:
You are currently using Forge 1487. The Shaders mod is not compatible with Forge 1469 and above.
Please downgrade Forge.
