Refs #17108.  Proxy commit for haysmark.  Add directory for new Change Impact analysis doh plugin to 1.9.
This reverts commit 7b47ddc4691bf1df2dcb33b0a0ed23b78acd26d7.
Add back submodule for less v1.3.3.

This is needed to get dijit/themes/claro/compile.js and dojox/trunk/mobile/themes/utils/compile.sh
working again.  Might be possible to install less via "npm install" instead but this is the path of
least resistance.  Less submodule was originally part of 8525a1a318033ea75bef49c54c1e91688aad49e9.
