* Add Per-Ship Class Wingmen Status Dot
This PR adds a ship info value `$Wingmen Gauge Dot Override:`, which allows modders to set wingmen status dots on a per-ship class basis. If no animation is specified then the default dot animation specified in the HUD table wingmen gauge is used.
Both EatThePath and Darius stated this feature would be useful, and it will also be useful for FotG.
Tested and works as expected, including on winged ships present at mission start and delayed winged ships.
* Add New Options to Wingmen Gauge
This PR adds two new options for modders to use in the HUD table for the wingmen gauge:
1) `Use Full Wing Names:` which draws the full wing name and does not alter the capitalization.
2) `Use Expanded Colors:` which use red, yellow, or green color to designate wingmen health (green 1.0 to > 2/3, yellow 2/3 to > 1/3, and red <= 1/3.
Also adds the bright red option to dead wingmen, which seems like it was missing before(?).
Tested and everything works as expected.
* correct string copy length
* fix out of scope case variable
If a wing has a hash symbol, it needs to match the squadron status gauge for the equivalent name without the hash. This could happen for in-mission jumps or cases where a wing leaves and comes back.
Also remove an obsolete function.
This refactors the tolower/toupper code to use standards-conformant logic, and also adds some helpful utility functions. Regular tolower/toupper must be supplied a value that can be represented as `unsigned char`, but the std:: functions are a bit more robust.
This introduces a new mechanism for handling bit flags. Instead of using an int (or two, or three) to write bits into, this uses the std::bitset in a wrapper class that accepts an enum class as input. This means that certain classes of errors we've had a few of in the engine, where a coder used the wrong set of flags or checked them against the wrong variable (SF_STEALTH vs SIF_STEALTH, for example) can now be detected at a compiler level rather than not at all.
