Roster should not lowercase addresses

[Rick Moen]

Within the WebUI pages, e.g., https://temp.balug.org/cgi-bin/mailman/admin/balug-test/members , the subscriber addresses are shown correctly with preserved letter case, e.g., my fellow list admin Michael Paoli's address is shown as entered, as <email address hidden> . By contrast, the roster at https://temp.balug.org/cgi-bin/mailman/roster/balug-test shows his address with lettercase converted to lower, as "michael.paoli at cal.berkeley.edu".

This is with a new installation of Mailman 2.1.8, and I've confirmed the same behaviour with several prior 2.1.x installations.

Admittedly, mixed lettercase in the local parts of e-mail addresses has no functional importance on _most_ SMTP systems, there is nothing in the RFCs requiring case-insignificance for local parts (only for FQDNs), so this loss of entered data could cause some users difficulties.
