**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.

Although it doesn't technically matter, for consistency this should probably use `:=` like the other assignments above. I think `:=` is also less surprising so it's good practice to use it unless `=` behavior is explicitly needed.
