Neogit autocmd for integration with outside plugins

[DonnieWest]

Use case:

Whenever neogit updates the state of git, other plugins that deal with git need a mechanism to be informed of changes. Otherwise, the state of those plugins become inconsistent with the actual state of the project.

For example, vim-gitgutter will still display code as uncommitted when actually it's been committed with neogit

Solution:

Create an autocmd for neogit that other plugins (or the user) can use to update those plugins. For example: we already have a __NeogitStatusRefresh function. If we expose that as an autocmd it would allow us to do:

autocmd User NeogitStatusRefresh :GitGutter to inform vim-gitgutter that our project state has changed

that is a cool idea!
