Used gas in dive planner points: Support for multiple cyl with same gas

Browse source 
In the planner if one adds two or more cylinders with the same gasmix
(e.g. back gas and bottom stage 18/45) the drop down and data in the
used gas column of the planner points table will be filled with a more
verbose string mentioning also the cyl number and the cyl type
description.
Makes it easier in such a case to select the right cylinder.

Introduces also a helper function which tells you if there is another
cylinder with the same gasmix as the provided cylinder.
This also has an option if it should consider unused cylinders or not.
