Add drop down to select the name display

[Crispae]

Give option to the user to choose, which type of name display they are looking for. This will provide transparency to see whether the name is normalized properly or not.

steps:

1. Add a drop-down menu in the input section
2. attach it to change in the config
3. Upon the change in the config, network will initialize again, (need to look for a way to load statically)
