Addition tracking clean up

[ascott1]

This:

• Detects which sidebar expandable is toggled (help vs. sxs)
• Only sends the relevant section when an inline interpretation is expanded
• Renames the sidebar expandable tracking events
• Only detects a defined term is closed when the user clicks the "close" button (rather than when a user opens a new term)
• Tracks the name of the term opened/closed rather than the term's id
• Changes the naming of the drawer toggle tracking to match other events
