Tabby show if any buffer in tab has unsaved changes

[spenserlee]

A few edits to the example in the readme.

The main change I thought was worth showing was adding a "buffer unsaved" display to the tab. I find this useful since sometimes I need to close out vim, but have forgot to save some files in a separate tab. Notice the only unsaved buffer is .tmux.conf in the example photos.

This config will show if any of the windows have unsaved changes, not just the tabs current window.

Other differences:

• Removes '' or '󰆣' is_current() icon, already covered by the highlight colour change.
• Remove window count for each tab (I think tabby should offer this as an API function instead of tab.name() always appending this information to the name)
• Neovim icon top left
• Remove current tab window names right side
