~~This has already been done with #938. This commit only changes version.c.~~

**vim-patch:7.4.231**

Problem:    An error in ":options" is not caught by the tests.
Solution:   Add a test for ":options".  Set $VIMRUNTIME for the tests so that
                it uses the current runtime files instead of the installed ones.

This is the test for 7.4.230. I have changed the $SCRIPTSOURCE/$VIMRUNTIME to match the Neovim project structure.
