Define a standard payload for writing and editing user genesets

@vincerubinetti I tried to organize the proposed fields as we discussed last week. Let me know if it looks alright.

Creating a new geneset

Required fields:	field	type	notes	default
name	string
genes	list	my_gene, ncbi, symbol, ensembl, or uniprot ids

Optional fields:	field	type	notes	default
description	string
is_public	string		True

Derived fields	field	type	notes
author	string	obtained from user authentication
taxid	integer	retrieved from mygene.info

Updating genesets

Optional fields:	field	type	notes
name	string
description	string
is_public	string
genes	list	my_gene, ncbi, symbol, ensembl, or uniprot ids. Overwrites previous list.
add	list	my_gene, ncbi, symbol, ensembl, or uniprot ids to add
remove	list	my_gene, ncbi, symbol, ensembl, or uniprot ids to remove

This looks basically like I imagined it would 👍

CLosing this, user geneset creation has been implemented.
