Patch to enable upgrade to latest HtmlUnit snapshots. Created a temporary dir
where various HtmlUnit snapshots could be tried without polluting GWT_TOOLS. 

IMPORTANT:
1. To test bug-fixes for Gwt 2.0 MS1, this commit needs to be reverted.
2. The do-not-commit-to-trunk dir should not be merged into trunk.
