In this update we use jsPacker.pl to combine and compress javascript
files. Instead of sending 6 javascript files totaling about 50KB, we now send 1 file totaling 21.1KB. After modifying any javascript files, run build-pack.sh to update srp.min.js. The login.html and register.html templates have been changed to send the one packed file. The file srp.js was modified so that it would pack properly. Necessary files from the perl version of packer are included, but they shouldn't be included on production web servers. The packer files are released under the LGPL.
