Fix title, git toggle, push target, showconf and restore bugs

- addnote: use the title passed on the command line instead of
  storing an empty one.
- USEGIT: test for the value true, so USEGIT=false actually
  disables git even when GITREMOTE is set.
- git: push to origin HEAD instead of a hardcoded master branch.
- configtext: print GITCLIENT, already defaulted to hostname.
- backup_restore: replace the malformed .git test, always remove
  the existing .git before copying the backup one.
- helptext/README: --backup requires a destination.
- README: add Development Approach section.
