[RTTY] Updated AA5AU RTTY Callsign Database

[Don Hill AA5AU]

I updated the RTTY Callsign Database today.  I added calls that showed in at
least 3 logs from combined ARRL RTTY Roundup and BARTG RTTY Sprint logs.

Please note that I have changed the naming convention for this file.  More
information on the naming convention can be found in the readme.txt file which
is included in the zip file downloaded from www.rttycontesting.com.

I also added calls received from the database update form
http://www.rttycontesting.com/database_form.html and certain calls which have
been advertised that will operate in the upcoming CQ WPX RTTY Contest later this
month.  Those calls were OH0I, P40G and SJ9WL.  To my surprise, two other
stations saying they will active during the contest period, J73CCM and L20H were
already in the database!  If you will be using a special callsign for the WPX
RTTY callsign or if your callsign is not in the database and you would like it
added, let me know.  I will try to do another update before the CQ WPX Contest.
This weekend in the FMRE (XE RTTY) contest.  Have fun!

Thanks to those that send me their Cabrillo logs.  These logs are used to update
the database.
