Some missing keys

Vibreoffice is a great idea however there are a couple of things that I find missing that can hopefully get added at some stage.

Probably easy to implement:

• gg to get to the start of the document and G to get to the end
• 0 as an alternative to ^ to go to the start of the line
• ~ to toggle the case of the letter under the cursor

Probably harder to implement:

• V for visual line mode
• / to jump to the next match of a word. This is the main way I get around in vim

As an aside that is not worth creating a separate issue for: it would be nice for the README to state that you have to enable vibreoffice in Tools→Add-Ons, as I didn't work that out straight away. (After reading the README again, it looks like this was in there)

I have suggested a patch for the 2nd item of this list ('0') in issue #14, FWIW...

It would also be nice if in visual mode "u" would set all the letters to lowercase and "U" would set all the letters to uppercase like it does in vim.
