Removed ghi and hub from bin

Since fossil is now the main repo used for projects, the git tools are no longer 
needed.
added bare-bones deploy script
added ability to rsync external tarballs to remote destination
added gnu packages to brewfile and updated manpath to include the man pages for these packages.
added check to ensure filename exists prior to assigning it to . THIS IS IMPORTANT. without this check, src would be empty and rsync would sync the root directory which is not good (unless it was intentional, then it is good)
added brewfile installation to osx setup script
renamed appledoc
added mkdir for destination directory in case it doesn't already exist.
added os-specific notmuch configs to account for differences in homedir paths. started using local certfile for offlineimap and was thus able to unify the os-specific offlineimap configs
added remote host parsing for ssh command
fixed git pull to ensure we're in the proper dir
added pre and post deploy hooks for local and remote nodes
split up offlineimap rc to account for differences in valid certificate file paths
removed extra tilde which broke zsh install script
updated mutt email directories
added email dir for txts
added removal of workdir if it exists from a previous job and fixed calls to remote server hooks.
updated hook calls to use hooks in the directory the script is called in
fixed nitelite-settings path
change mail location to centralized mount
