Reacts to BufWritePost and CursorHold events. (Silently) executes any
executables of the form .[eventname].vimhook. Event name is case
insensitive. The following filenames will all be executed after a
BufWritePost event:

- .BufWritePost.vimhook
- .bufwritepost.vimhook
- .BUFWRITEPOST.vimhook

At the moment these files must be executables (chmod 755).
