If I run a flow from within Salesforce using a button, it will display in a lightning skin. However, if I launch that flow via a Visualforce page, it displays with the classic skin. Is there any code I can add to the Visualforce page to make it display in with the lightning skin? 

So I am needing to upload many global picklist items for conversion for our existing database key value pairs
using the following documentation https://releasenotes.docs.salesforce.com/en-us/winter16/release-notes/rn_forcecom_general_global_picklists.htm
Currently , when you create a picklist, you enter the values for the picklist separated by a line

so for instance, body part picklist is 

face
ears
neck

after you create the picklist, you can go in and edit each individual picklist item's "api name" , essentially making this a code for a key value pair

but if you have a list of 500 picklist values and 200 picklists that need to be created, this is almost infeasible

is there a way to on picklist creation set the key value pair rather that the value setting both the value and api name so i can do integrations more smoothly
