Repeat last toolbox command

[DanWlker]

Add functionality to repeat the last executed command

Considerations:

1. What to do for functions or commands that require variables?

• another variable for each command to decide when repeating whether we should prompt users for input again?
• different keybinds, where one will prompt for input and another will reuse?
• what should be the default?

2. What is a good default keybind

• currently <leader>st is cause I'm using kickstart nvim, so binding it with telescope seems logical, but if repeat were to be used, need to consider whether there is a more logical binding
• <leader>str for repeating
• <leader>stt or <leader>sts or <leader>st for normal toolbox, note st will have slight delay if used with str

3. What to do with functions executed on top of visual selections

Need to think about it
