Rename admin user to sympl, secure permissions
Replaces the 'admin' user created by Symbiosis with a user called 'sympl' instead - less chance of a username collision, and if the users home dir is not /srv, it means we can store things like config files there safely.
Things to remember:
Backup paths will need checking to ensure
/srvshould be set to sympl, and config files should be set to be owned only by sympl.
- Must run through domains
- Sympl should be in the www-data group, and public (and subdirs) should be owned by www-data, with permissions set 664.
- things like sympl-ssl should be okay with the dir being owned by www-data
- the FTP user should be changed to www-data
- common apps (vim/htop) should be added to sympl-core recommends
- sensible config defaults should be added to sympl-core for the sympl user
