proposal: improved import declaration

[eao197]

	Hi!

The proposal is to allow writing:

import <module-root>.{<name>[,<name>...]};

For example, instead of:

import tango.io.Console;
import tango.io.Conduit;
import tango.io.FilePath;
import tango.io.FileSystem;
import tango.io.Stdout;

simply write:

import tango.io.{Console, Conduit, FilePath, FileSystem, Stdout};
