Better docstring for haskell-hoogle
Colorize hoogle output, and run hoogle synchronously

Hoogle searches locally and runs quickly, so it rapidly produces all
its output. It's better, then, to insert it in one shot into the
result buffer (now called "*hoogle*" instead of "*help*").

And if we pass the "--color" option, we can then get more readable
output, provided we pass it through "ansi-color-apply-on-region".

Closes #299
Store original position when jumping with M-. to allow return with M-*
Remove redundant progn
Add haskell-interactive-switch-back, so C-c C-z becomes a toggle
