"Copy Full Path" option in context menu is causing confusion among users

Describe the feature request

Update context menu options for copying links/paths to files and folders to prevent user confusion; specifically:

• remove or rename "Copy Full Path" (Travis suggested "Copy SeqDev Location")
• add "Copy Link to File/Folder" (same as copying URL)
