Summary: Force megatest to fail if application sizes changes by more  
than a configurable amount

Performance Tuning ongoing)

Details:
     Enhanced the 'Netsize' program that calculates the size of urls  
retrieved and
     compares this to a previously stored version.  Now, if the  
percentage change is
     out of the acceptable bounds, the program will report a failure.
     This program is run by doing 'ant appsize' at the top level.
     It is also triggered by a run of megatest.

     Two values can be set, and are preconfigured in the top level  
build.xml:
        -- an overall acceptable size change percentage, currently set  
at 5%
        -- a default size change percentage enforced per url and per  
application, currently set at 20%

     An 'application' is defined by this program as a set of URLs  
listed and grouped by name
     in the input configuration file (test/appsize/appsize-input.txt).
     The change percentage is based on the byte count values  
previously recorded,
     also in the same input file.

     Each run of 'ant appsize' produces a file test/appsize/appsize- 
output.txt that represents
     a new baseline and can be used as a new input file (appsize- 
output.txt is NOT in svn).
     It is expected that at each release (or when appsize begins to  
fail regularly
     for a good, known reason), appsize-output.txt can be committed to  
appsize-input.txt
     to thereby reset the baseline.

     There is general information in test/appsize/readme.txt (which  
has also been updated).
     That file is referenced by the build.xml comments.

     NOTE!!  this change includes a reversion of test/appsize/appsize- 
input.txt to a previous state

     Using the latest version of this file makes it appear (to me)  
that the application has reduced substantially
     in size, and that is certainly not the case.  I suspect that  
later versions were generated
     by running against a server that does not have compression turned  
on?  This does mean
     that megatest will fail until the server is fixed.
     Notes for configurating compression are in test/appsize/readme.txt

Tests:
     ant megatest
       changed values in test/appsize/appsize-input.txt to simulate  
failures

     nightly build (pending)
       !!!! This will FAIL until compression is turned on for the  
build server.  See NOTE above.
