Update StatusRowContextMenu to include a "Copy Text" option (#36)

* Add option to re-hide spoiler content after expanding

Uses the same logic as the "Show more" button, but in reverse. This allows a user to hide the content that they expanded.

* Use .toggle() method instead of multiple if statements

* Update StatusRowContextMenu to have Copy Text option

* Update pasteboard string to contain rawText status
