[Seaside] Generating a random string

[Boris Popov, DeepCove Labs]

Sven,

Someone ended up writing the below for VisualWorks' version of
#atRandom, so I skipped using it in an example,

atRandom
 ^self atRandom: Random new

| size |
size := 32.
String streamContents: [ :stream | 
	size timesRepeat: [ 
		stream nextPut: '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ
atRandom ] ] 

'TSBY6AHHXF5YYJDNLOFE7P8C4V2OMA8P'

This is a bit slower (due to internal locking), but less code.
