Use the drop down for editing the tank use in the gas list in both the equipment tab and the dive planner. The tank use column is now available in the equipment tab for all dives and not just CCR dives, as 'not used' is a valid entry in both cases. However, if the current dive is an OC dive, only 'OC-gas' and 'not used' are shown. There still seems to be a problem that in some cases, when opening the planner after selecting an existing CCR dive the drop down in the planner does not list CCR gas uses - for some reason `displayed_dive` does not seem to be updated correctly on opening of the planner. But I have not been able to reproduce this consistently, and changing 'Dive mode' fixes this. Signed-off-by: Michael Keller <github@ike.ch>
