Add a "Delete Tag" button

[dv297]

As a member of the Graffiti Abatement Tracking Program I want an icon to delete tags so that erroneous or redundant tags can be removed.

We will know when we are done when

• on iOS
  • you can swipe left on the tag list to delete an item
• on Android
  • you can hold the list item which will bring a new menu to delete the item

I think a table view can assist here. https://github.com/aksonov/react-native-tableview#features

Note the use of the trash can icon for deleting the tags.

For iOS, let's use both sliders and delete buttons.
