core: allow separators ,; after degree-style coord Tweak the Lat/Long coordinate parser to allow coordinates of the form: 12.1049° N, 68.2296° W The coordinate parser works by tokenizing coordinates one at a time. Consequently it is invoked twice on user input to get latitude and then longitude. Normally, after parsing the first coordinate, intervening characters such as , or ; and any whitespace would be discarded from the input before parsing the second coordinate. Prior to this patch, if the coordinate format was in degrees followed by a sign (N is a sign in this example), the parser would skip the bit of code that fast forwards past any intervening separators and whitespace (, in this example). This resulted in coordinates of this form not being accepted, because the second parse would start with , 68.2296° W and reject this as an invalid coordinate. To rectify this, the bit of code that fast forwards past separators and whitespace has been broken out from the tokenization loop and performed as a final step after a single coordinate has been completely parsed and validated. Doing it this way makes it independent of the state of the tokenizer, so that the fast-forward code will always execute once a coordinate has been successfully parsed. I've also centralized the list of allowed separators into its own static string; this is necessary as part of the patch but should also make allowing additional separator characters between coordinates trivial in the future, if needed.

Planner: Improve Gas Handling in CCR Mode. This has become a bit of a catch-all overhaul of a large portion of the planner - I started out wanting to improve the CCR mode, but then as I started pulling all the other threads that needed addressing started to come with it. Improve how the gas selection is handled when planning dives in CCR mode, by making the type (OC / CCR) of segments dependent on the gas use type that was set for the selected gas. Add a preference to allow the user to chose to use OC gases as diluent, in a similar fashion to the original implementation. Hide gases that cannot be used in the currently selected dive mode in all drop downs. Include usage type in gas names if this is needed. Hide columns and disable elements in the 'Dive planner points' table if they can they can not be edited in the curently selected dive mode. Visually identify gases and usage types that are not appropriate for the currently selected dive mode. Move the 'Dive mode' selection to the top of the planner view, to accommodate the fact that this is a property of the dive and not a planner setting. Show a warning instead of the dive plan if the plan contains gases that are not usable in the selected dive mode. Fix the data entry for the setpoint in the 'Dive planner points' table. Fix problems with enabling / disabling planner settings when switching between dive modes. Refactor some names to make them more appropriate for their current usage. One point that is still open is to hide gas usage graphs in the planner profile if the gas isn't used for OC, as there is no way to meaningfully interpolate such usage.
