Change current working directory with Lua

[sineemore]

Need something like fs.chdir to change current working directory with Lua.

Example usage:

local err = fs.chdir("/this/path/exists")
assert(err == nil, "Failed to chdir to existing directory")

local err = fs.chdir("/no/such/path")
assert(err != nil, "Chdir to nonexistent directory succeeded")

err should be string describing the failed syscall.
