* perftools: removed brackets in python return calls
  * perftools: added 'coding: utf-8' comment to all python scripts
  * dp: remove persistent IFS setting; it's so easy to return
    from a function without setting it back
  * dp: ongoing development of perf-tests
  * dp: added perf-tests
  * dp: moved ChangeLog to doc subdirectory
  * dp: changed all scripts to use bash instead of sh
  * add: made executable
  * all: removed all the empty 'doc' directories as there is
    now one single ChangeLog
  * neighbour-wlan-uptime: created
  * all: fixed some more sort and tails
  * all: fixed calls to sort and tail in line with warnings
    which newer versions of these GNU tools produce.
  * web-referral-judith: removed an echo to tty 
  * switched to single ChangeLog for all dp submodules
  * added check that the entry being written is complete; this
    will hopefully reduce the number of conversion errors and
    manual edits.
  * added a missing quote (no idea how it went missing!)
  * removal of fixed internal on X axis, so that gnuplot can
    (however it does it) set the tic interval to the irregular
    once-per-calendar-month.
  * fixed a lower Y max. The 20Tb which it once peaked at is
    a unsatisfactory permanent maximum.
  * report line number on which errors occur on the conversion
    of raw-to-plottable data.
  * rewrote in perl for speed
  * created as subdirectory of 'dp' module
  * switched to using perl for conversion of 
    balances to gnuplot-able datafile as it was
    taking much to long
  * removed regular explicit X tic interval and
    instead rely on gnuplot's own better ability
    to place tics at the start of calendar months.
  * created as subdirectory of 'dp' module
  * created as subdirectory of 'dp' module
  * copied from web-referral (which has since been renamed
    web-referral-alexis)
  * renamed modulette to web-referral-alexis as there
    is now a web-referral-judith too.
  * apache log files relocated to /var/logs/apache2
    for official Debian package, and change from
    '_log' to '.log'.
  * removed explicit X tic interval and instead rely
    on gnuplot's own better ability to put tics at
    start of calendar months.
  * ignore internal URL redirections (e.g. a requestor
    of .../STABLE/... will submit *two* requests which
    contain the requested URL and the (e.g. Google)
    non-local referrer. This artificially raises the
    number of hits. So this is now filtered out.
