Implement Iter(Dir) and each(Dir)

[ilyash]

... which should iterate over Path objects in that directory

[ilyash-b]

After implementing this. The following should work:

Dir('.').each(F(entry) {
  ...
})

for entry in Dir('.') {
  ...
}

See:

• Iter.ngs
• dir() function in stdlib.ngs

Notes:

• If Iter(d:Dir) is implemented, implementing each() should be trivial as roughly: F each(d:Dir, cb:Fun) d.Iter().each(cb) (not tested)
