Subject: [PATCH] Update documentation and install scripts to reflect new
 minimum Python requirements.

Documentation and install scripts now instruct older Python users to upgrade
their Python version or install older versions of autojump.

'install.sh' now gets a -f|--force option, which makes the install ignore
Python dependency requirements.
