"Uncomment" menu item fails on Linux/Wayland/GTK3

Selecting text and using the "Racket|Uncomment" menu item does nothing on Linux with Wayland and GTK3. With `PLT_GTK2=1` set, it works correctly.

Use `extract-procedure`.

This should fix #18 but doesn't for reasons that I don't yet understand.

``` #lang racket (require soft-contract/fake-contract) (define (f x) (/ 1 (if (= x 100) 1 (- 100 x)))) (provide/contract [f (integer? . -> . number?)]) ``` produces ``` Contract violation:...

``` (module m racket (define v (/ 1 0))) ```

Reduce expansion from type and contract generation.

This reduces zo size in `plot-gui-lib` by about 11x.

Add `unsafe-make-vector`.

On Racket CS, this omits the check for large allocations and lowers to a less-checked Chez operation. Needs tests and docs, but opened for initial feedback.

Some small optimizations in schemify to optimize code that uses multiple values, and more operations in the treelist benchmarks that use gvectors.
