Improve workload reports to help identify under workloads

Hi,

At present time in v11.1.2, workloads reports don't include vacations managed under projeqtor. But these reports aim at helping identifying under/overloads on resources. For this purpose, I don't want to have to analyse vacations to figure out some apparent under loads are in fact vacations. It would be nice to add a chackbox to add vacations in the workload reports or to add a line with vacations in order the total take it into account, possibly with a sub-total without it.
