Add a new method 'processDefinitionIdLike' to TaskQuery

Hi,

it's not possible to create a task query to find all tasks of all versions of a specific process because TaskQuery append a where clause with a = operator and not a like operator

if (processDefinitionId!=null) {
appendWhereClause("task.processInstance.processDefinitionId = '"processDefinitionId"' ", hql);
}

May be, it's a good idea to add a new method like 'processDefinitionIdLike' to TaskQuery object in order to append a where clause like that :
if (processDefinitionIdLike!=null) {
appendWhereClause("task.processInstance.processDefinitionId like '"processDefinitionIdLike"' ", hql);
}

Thanks in advance
