BROKEN PARITAL CODE - time scales

pending: all of absolute implementation
pending: abs/rel toggle

bug: clicking the number input field closes form

Partial implementation of multiple timescale selection. Also splits out navbar
buttons into items for modularity
Relative time - complete. Uses `&time=relative` query string
Absolute data picker implemented

uses `&time=absolute`, and the eonasdan bnoostrap datetimepicker
Add changer for time scales. Save route changes
Have time changer use all three time types
bump ver
test vers change
prevent index out of bounds error
Cleanup time selector forms

Have a toggle to change only
No validation on input as yet, apart from what datetimepicker/moment provides
by default.
Use jquery.form-validator for basic validation

Used for both the integer input on relative time, and the date formats on
absolute time
update specs to suit change in homepage
Give the stop dropdown a real name
