Show keyboard shortcuts in a consistent order in help

Browse Source 
Perl's hash variables are not ordered so each
time we run the CGI script for the help page
we may get a different order.

This caused bindings and names to appear
differently on each reload.

To fix this sort by keys when generating the
shortcut tables.

Fixes #133
