roundup-server.ini and admin_guide.txt contain description of log_ip directive that was probably replaced by log_hostnames option.

In this the following FAQ.txt option is also outdated:
http://roundup.sourceforge.net/doc-1.0/FAQ.html#roundup-runs-very-slowly-on-my-xp-machine-when-accessed-from-the-internet

debugging.txt is outdated too. It documents unused environment variables HYPERDBDEBUG and HYPERDBTRACE.

Related to Issue2550545 (README.txt: Instructions for building the 
documentation outdated.)

debugging.txt already has the HYPERDB stuff removed.

I generated a new example server config file using:

 roundup_server -p 8017  -u roundup --save-config  demo=/trackers/demo \
    sysadmin=/trackers/sysadmin

and included it verbatim (including keyword explanations) in the
admin doc. Then annotated a few of the keywords with some info that was not
in the explanations.

I removed the XP doc from the faq. XP is obsolete and the log_hostname
should be referenced instead. Default is of so unlikely to be a problem.

Also fixed a couple of mispellings in:
  roundup/configuration.py
  roundup/scripts/roundup_server.py
