Bug 19128 - Handling whitespace in aliases 

Add a new attribute `ignore-blanks' to <test>.
When this is set to "true", any blanks in the string will be ignored
on comparison.  This takes effects for compare="eq" or "not_eq" only.

Also changed the behavior of the comparison on <alias> too.

succeeds if any value associated with the property matches the test value, or
"all", in which case all of the values associated with the property must
match the test value. When used in a &lt;match target="font"&gt; element,
