Rename and delete files and directories in the Web IDE

I should be able to rename and delete files in the Web IDE so that I don't have to leave the Web IDE to the repository file list to do this.

Proposal

• add delete button to file/directory drop down in file tree
• add rename button to file/directory drop down in file tree

Design

• Get rid of the plus icon, and replace it with a menu icon

• For files, there can already exist icons in the right side of the list element. These should be shoved aside with a small animation similar to:

• Files menu should consist of:

  • Rename

  • Duplicate (separate issue)

  • Move (separate issue)

  • Delete

• Directory menu should consist of:

  • New file

  • Upload file

  • New folder

  • SEPARATOR hr

  • Rename

  • Duplicate (separate issue)

  • Move (separate issue)

  • Delete

• The menu will display dedicated icons for each item, svg's will be available in a bit

• The branch has always visible options, these are not extended here/much, so we can display them directly with dedicated icons.

This results in:
