This significantly improves performance on a loaded machine

Since we now use utf-8 internally in the database,
we must convert to and fro from user and filesystem
input and our database. Of course to make things worse,
python 3 completely changed the way python handles unicode.

This is an attempt to do things correctly

example:

if you have /tmp/vv/vv and want to specifically target it, you can now type
j vv vv
and it won't match /tmp/vv.

Still needs a migration script

This should correctly merge Tanguy's XDG changes (thanks!) into the new
codebase.

Update to Readme

Fix PROMPT_COMMAND for compatibility with OS X Lion

Fix install.sh to check for sourcing of .bashrc

It now uses $AUTOJUMP_HOME if set, else $XDG_DATA_HOME/autojump if set,
else ~/.local/share/autojump.

Instead of updating $PROMPT_COMMAND by appending $AUTOJUMP with a leading
semicolon, prepend $AUTOJUMP followed by a semicolon.

It is unlikely (and frankly wrong) for anything to set $PROMPT_COMMAND to
begin with a semicolon, so this modification should not cause conflicts
where the previous version does.

Use pickle protocol 2.

This ensures that autojump works when the default python interpreter is
changed, e.g. by virtualenv.

Should fix issue #39

autojump is now packaged for Debian too, and will reach Ubuntu.
