Feature request: new Archive action

[arosiek]

It would be nice to have possibility to hide some snippets instead of removing them. For example I'm using some command in project A. When finish my project I would like to hide all commands from the project to avoid too much mess but I would like to keep the command for the future (for example if my future project would be based on same technology/framework).

AK:

• delete functionality stays as it was
• new button added: Archive
• checkbox added in filter menu: include archived
  • if unchecked filter ignore archived snippets
  • if checked filter includes archived snippets
