* This change is to create an argument version of the config operation_timeout.

* Created the set of auto-completes that Bash returns with '-<tab>' and '--<tab>'. Made sure that --synchronize and -m/--monitor can't be used together based on the "#exclude some mutually exclusive options" in complete.bash file.

* Add the FISH_COMPLETION_DIR variables and the install and remove instructions for the onedrive.fish completions file.
