Another monster patch.  Change each tab to 4 spaces in the staff client xul, html, and css files.

Did this to effect the change:

	find . -name '*.xul' -exec sed -i 's/\t/    /g' {} \;
	find . -name '*html' -exec sed -i 's/\t/    /g' {} \;
	find . -name '*.css' -exec sed -i 's/\t/    /g' {} \;

Statements like dump('\t\tFoo\n'); are unaffected.

I imagine we'll need to realign and reindent things as we encounter visual ugliness.
