Dynamic for urls - initial form values, misc

/ui/deployment/[int]/ url and /ui/ urls work except the deploymentID field disappears after /ui/ form is submitted. Default for datetime range is the last day for which data is in the database. Activity and Likelihood defaults are min and max. Automatically show data for deployment/int. Cleaned up mouseover for markers.
