Accession Upload Auto-Generated Lists

[dwaring87]

When a user uploads an accession file through the website, an auto-created list is generated with the accessions in the file with the name "AccessionsIn{file_name}{timestamp}".

Changes to make:

• allow the user to optionally create a list of accessions from the file when uploading a file
• the user can specify the list name
• if the user does not opt in to creating the list, the auto-created list should be removed after verifying the file upload
