Factor common where methods out of the DSL classes. THis will allow for an easier implementation of future where support such as "exists". � Conflicts: � src/main/java/org/mybatis/dynamic/sql/delete/DeleteDSL.java � src/main/java/org/mybatis/dynamic/sql/select/CountDSL.java � src/main/java/org/mybatis/dynamic/sql/select/QueryExpressionDSL.java � src/main/java/org/mybatis/dynamic/sql/update/UpdateDSL.java

This turned out to be a fairly substantial change. Previously the where support assumed that criteria were always column based. With this enhancement, "exists" and "not exists" can be used in where clauses for any statement and can be nested with "ands" and "ors" as per natural SQL.
This enhancement is compatible with existing code at the source level.
