Convert write database operations to handle boolean formulas This commit follows up from my previous work to support arbitrary boolean formulas in queries. As done with Query, now Update and Remove have been modified to handle these arbitrary Expressions in their "where" methods. One issue I'd like to bring up is that these methods previously accepted conditions using only the EQUALS operator. As far as I can tell this is an unnecessary restriction. Now with the move to simply accept an Expression argument, updates and removes can handle arbitrary where conditions. The Qualifier class and Criteria enum have been removed since they are no longer used. Reviewed-by: jerboaa Review-thread: http://icedtea.classpath.org/pipermail/thermostat/2013-June/007082.html
