mod_adhoc_dataforms_demo: Add compat with 0.11 (vs trunk api change) The name of the "access for anyone" permission level changed from "user" in 0.11 to "any" in 0.12/trunk to make it clearer that it's basically unrestricted. This is unfortunately not backwards-compatible. Thanks to Sam for stumbling upon this during a demo.

This module logs events where more than a certain amount of CPU time was
spent.

``` lua
log_cpu_threshold = 0.01 -- in seconds, so this is 10 milliseconds
```

Uses the Lua
[`os.clock()`](http://www.lua.org/manual/5.2/manual.html#pdf-os.clock)
function to estimate CPU usage.
