[2.1.9] requiring a relative lua path does not cache the file

[Quezler]

In 2.1 a required lua file only runs once, which means these all return the same instance:

require("thing")
require("__modname__.thing")
require("__modname__/thing")

However, relative paths are each seen as unique:

require("__modname__/./thing")
require("__modname__/././thing")
require("__modname__/./././thing")

The expected behavior is that the path gets resolved to an absolute path first. (which also gets used when logging from within that file, vs it also being relative)

Thanks for the report. As a simplification these types of paths will simply be disallowed for the next release. As far as I know there is no legitimate reason to ever use them.
