Move less used actions from main context menu in submenus

[teamcons]

Problem

Less used actions, such as "Send in mail", create noise when looking for common actions such as "Move to trash" or "rename"

Proposal

Identify a list of actions that could be moved into a "More actions" submenu, below of "Open with"

i may edit this FR once i have access to our eOS puter, but off of the top of my head:
-Send by email
-Create shortcut

This would make the file manager more focused, and in the same breath provide room for extending it

Prior Art (Optional)

Nemo, in Cinnamon, has a "More tools" where user can expand with community-made "Actions"
Nemo and Nautilus have a scripts folder, allowing users to create custom actions on files via shell scripts

I agree the context menu for file items has become rather long. I think most items provided by contractors and plugins could be moved into a subfolder. These include "Send by Email", "Send by Bluetooth", "Compress", "Apply color tag", "Set as Desktop background/Wallpaper". Incidentally I noticed there now seems to be two items that do the same thing (set the background) so that needs sorting out. I'll raise a separate issue for that.

Flagging for design team input before implementing.
