Currently the event type code uses libdivecomputer's flags to differentiate between events. Make this explicit and extract the event severity. The reason is that later we want to be more explicit about showing/ hiding events and thereto we must format the name of events. Moreover, this encapsulates the complexities of extracting the severity in the event code (that used to be in the profile code). Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
