Milestone name change doesn't reflect in ticket_change table

[khundeen@…]

When changing a milestone's name, the milestone name in ticket_change table wasn't changed.

This cause problem when analyzing the ticket changelog again the milestone whose name was changed. It would be great to change the milestone name to the new one when milestone name is changed.

I think this is problem in general in the db schema: names are used to link rather than unique ids. Name approach may shorten SQL & make it more readable, but it causes problems like this.

I'm quite sure that using webadmin to change milestones or components will have the same problem.
