Revert "Allow setting arbitrary options via 'vis_*' keys"

This reverts commit 556370f35d4486ad01d549a7f6ff24618a547908.

It looks like nobody is interested in using 'vis_*' keys.
If that changes, drop me a note to revert the revert. Until
then, not having this feature seems to be the cleaner way.

-### Setting arbitrary options
-
-To some it might be convenient to use editorconfig files to set arbitrary
-vis options. Therefore, the vis editorconfig plugin uses the `vis_`
-prefix in keys as an interface to anything that can be specified with
-`:set`.
-
-Instead of running `:set spelllang en_US` after opening a file, for
-instance, one can also add
-
-    vis_spelllang = en_US
-
-to the appropriate section of an editorconfig file.
-
-Note that keys in editorconfig are case-insensitive. The specification
-suggests to lowercase them. Therefore, it is only possible to use this
-mechanism for lowercase options. If you really need to use upper or
-camel case options, add an alias to your `visrc.lua`:
-
-```lua
-vis:option_register("snake_case_option", "string", function(value)
-  vis:command("set camelCaseOption " .. value)
-end, "Alias for camelCaseOption")
-```
