Feedback from updated staging site for DMS/JBrowse.

@samrichca WONDERFUL WORK!!! The site is looking amazing, just one tiny update, if too much work please ignore as it's a very minor change.

[from @patrickdsantos] :

1. Change placement of date selector fields from right align to left align. See example below.
