Jazz SCM Alias Id's roll over to zero, not 1000 as advertised.

Seen in RTC 4.0.2.
The aliasId that the SCM CLI client creates starts at 1000 and increments by one for each change needed. It, according to IBM, is meant to roll over from 9999 to 1000 again (choosing the oldest and least used value). However, it does not. It rolls over to 0.

This in itself is not a problem, however, as we (currently) treat it as an Int, for an aliasId of (for example) 23, it needs "0023" (with the leading zeros) not "23" (if we treat it purely as an int).

So, the solution is to print the alias id with leading zeros.
