Trailing spaces in a milestone's name prevent assigned tickets to show up

[adrian.gygax@…]

If a milestone's name contains trailing spaces, assigned tickets won't show up in the Roadmap view. This problem is reproducable by these steps:

1. Create a new milestone with a trailing space in its name (i. e. "Test Milestone ")
2. Create a new ticket and assign it to the newly created milestone
3. Go to the Roadmap. The ticket won't shop up in the milestone's ticket overview

If you add a trailing space to the name, already assigned tickets are correctly handled and show up. However, newly created tickets again won't show up.

I'd suggest to automatically truncate trailing spaces from milestones' names.
