Recommit of rev. 1507 (was part of MWDAM-1221). However, this also helps to speed up the reaction time of the tree after initial click. Related to Issue [MWDAM-1191]
Adapted to review comments, replaced "standard" progressDelegate by DamEngine version for every use of progressDelegate. This is a quick fix for the progress bar problem.Related to Issue [MWDAM-1196]
Implemented the correct progressDelegate, removed obsolete double entry for CalculationFinished in Translations.xml. Added dialog for calculation time. Note: as Import used to use same progress control as Calculation, this is now still to be fixed. Related to Issue [MWDAM-1196]
