[sldev] RFC: design proposal for VWR-1071

[Cypren Christenson]

Hello everyone. I've been following the list for a while and finally
decided to get my hands dirty and contribute to the codebase. I've
picked out a seemingly very simple feature add to start with, and
wanted to post my proposed solution so that wiser, more experienced
heads could possibly caution me about any pitfalls that I may be
rushing into, given my inexperience with the project.

VWR-1071 (http://jira.secondlife.com/browse/VWR-1071) is a fairly
simple request: add a method for users with multiple SL
accounts/identities to store their credentials and quickly pick
between them at the login screen, instead of only having the last
login credentials saved. Since there are multiple text input fields on
the login screen, my inclination is to change the First Name field to
a combo box rather than a text box, and display both a first and last
name in the dropdown list. Selecting an entry from this list would
then populate all three fields (or only the name fields if password
saving is not enabled). The list would simply hold a history of all
logins made by that user account on that computer.
