Use the ST monad for running the linter
...
The only place where IO is needed is to read the source file when reporting
errors, so for now I just use unsafeIOToST for this one effect, since it
refers to data that should be immutable for the duration of the linting run.

Add checkExpr, which checks for errors in Nix expressions
...
This allows us to pass 10 more of the NixLanguageTests, so that after parsing
a file containing "x: y", we can report that y is undefined.

subdirectory for main to avoid redundant compile
...
Cabal builds the library files twice if the main executable and the
library share the same hs-source-dirs. Moving the main executable source
code to a subdirectory avoids this issue.
