Removes Doh test
Updates loader.js block

Changes to loader.js to support fixed paths were
never copied into the minified version of loader.js that
is embedded into runtimeLoader.js.  This updates the minified code.
Now tests for either wm.packages or common.packages
Fixes to queryVar
1. queryVar is now ignored; this is not meant to be written
to widgets.js (not yet anyway)
2. setQuery now tests if queryVar.isEmpty() instead of testing if
its false.
Fixes support for caseSensitiveSort=false
Only queries in notify if not _updating
Reformat Code
Now writes app-level components before writing page components
