Fixed bug in getModifiedDate method of Wsh adapter for FileSystem service.
Consolidate _params, _paramOverrides, and _env in the correct way in order to address the issue where specifying an override for staleBefore when running a build script from the command line wasn't working correctly.
A much more elegant way to deal with the builder input last modified dates and the stale before, and how these influence whether or not a particular URL needs to be built. This change addresses an issue that was being seen where the memory URL files being built were having their modified date set to the time the file was built, which was causing the memory builder inputs to other built files to incorrectly invalidate their build results. The better approach is to set the modified date of the in-memory built files to the max of the modified dates of their inputs along with the staleBefore date.
Some TO DO doc updates.
Added support for the builder inputs being an array, string, or an arbitrarily complex data structure.
Created a Uize.Built.Util.moduleAsText utility method for serializing modules to text form.
Fix for an infinite recursion issue in IE with "fixed" events. I guess the fix method really fixed them goooooooooood. Thanks, Ben, for catching this one.
