Separate guarding functionality into base module

[CrabDude]

There are 4 parts to trycatch:

• Fixing callback context (EE handlers at time of listen vs at construction)
• Guarding core from userland errors and fixing
• Long-stack-traces
• Async try/catch

trycatch should be refactored into the separate modules, with trycatch at the top of the abstraction stack.

Perhaps, Error.longStackTraces should be used instead of trycatch.configure.

I'll do this sometime soon since I'm working on my own company now.
