Add a "Service" item to Bike Components list
This item should be able to be selected multiple times per bike. Linked to date (as all other current items currently are) it will allow for easy tracking of service intervals.
Also allow replacement items to be replaced multiple times per bike. This will make it easier to track how long an item lasts that is likely to be replaced multiple times (eg. Tires).
Also notice now that "Retire" does the same as "Delete" for a component. I would have expected a 'retired" component to still be in the history log of the Bike component list.
