acs-developer-support-procs.tcl

Fun with developer support!

1. Added a button to turn template profiling on/off.

2. Moved templating information to the request information page. It was
confusing having it work differently than db and other information. If,
for instance, you clicked on a request link in the developer support
index page, you'd get the db timing information for that request, but
the profiling stuff would come from the footer - and would be the profile
information for displaying request-info.tcl/adp, not for the template
served for that request. Oops.

3. Simplified the ds_profile proc since in practice it only is used for
profiling templates.
