Bug 24110: Do not html filter TT vars when dumped

DumpTemplateVarsIntranet and DumpTemplateVarsOpac are devs tools to
display the variables sent to the template. They should not be filtered
otherwise it's getting complicate to read.

For instance: $VAR1 = { var => val }

Test plan:
Turn DumpTemplateVarsIntranet on
Go to the main page
Show the source of the page
Confirm that the variable are displayed as it and not filtered
