Programmatically download icons?

[tinchodias]

For the case you are interested:
For fonts, which are far smaller files, I used this way to do it:

ZnClient new
			url: aUrl;
			numberOfRetries: 5;
			timeout: 100;
			logToTranscript;
			downloadTo: downloadDirectory.

Mostly a suggestion, please close the issue when you consider!
