hash algorithm speeds up exists() by 10% and intersectionSize() by 8%.

2. SOLR-115: Solr now uses BooleanQuery.clauses() instead of
BooleanQuery.getClauses() in any situation where there is no risk of
modifying the original query.

Bug Fixes
1. SOLR-87: Parsing of synonym files did not correctly handle escaped
whitespace such as \r\n\t\b\f. (yonik)
