Miscellaneous improvements to FindWorkEffort screen

Attached patch add miscellaneous improvements to FindWorkEffort screen:

1. Add "noConditionFind" field with value "Y" to FindWorkEffort screen to show results without click "Find" button
2. Change response type of deleteWorkEffort from "view" to "request-redirect", so that user can stay in FindWorkEffort screen after deletion
3. Remove "buttontext" widget style of workEffortId column, as text of this column also contains workEffortName, and it may be very long and even wrapped for two lines, "buttontext" does not fit it quite well
4. Change ListWorkEfforts from "form" to "grid", and enable "sort-field" for most of the columns (except "description")
5. Change "workEffortId" field text from "${workEffortName} [${workEffortId}]" to "[${workEffortId}] ${workEffortName}", to be consistent with the sort order, as this column is sort by workEffortId
