Samuel Bowman d8bac4dbda Spreadsheet: Move menu and action code to initialize_menubar() ...

Previously, all the code to add menus and actions was in main().
This was messy and didn't allow us to reference the actions from
SpreadsheetWidget, which is needed in order to add a toolbar.

This commit moves the menu and action adding code to method on
SpreadsheetWidget called initialize_menubar() which is based upon
applications such as TextEditor which have identically named methods
doing the same thing.

In additon, clipboard_action(), previouly a lambda in main(), has also
been made into a method on SpreadsheetWidget since it would otherwise
be destroyed when it goes out of scope. (This was previously avoided by
declaring the lambda in main() so it's always in scope.)
