Values now replaced recursively, added fontification for replacements
Added the "let form" check. If in a let form, do not substitute.
Added function to substitute variables in let forms
Only substitute variables in let forms if they clash with the arguments
Fix one useless iteration when "name" = "nil" (check the symbol instead)
Merge branch 'master' of git://github.com/nicferrier/litable
Destupidify the litable-find-function-subs-arguments function.
All overlays are now in a single list. The subroutines now print the partial result too.
Refactor result-printing into a function.
Add support for let-binding definition substitution
Refactored exception-form handling
Remove letcheck dependency, bump version
Added overlay priority to properly order the sub-results if there are multiple evaluations
Print the input arguments unevaled. (useful when invoking the same function multiple times)
