More bug fixes
Changelog since v0.3.1:
- fixed an issue with slot keys not always being processed properly;
- wheel: fixed incorrect reaction to out of bounds angle in second wheel;
- removed a message for obsolete key bind which may have caused "Alias tried to recurse" console error.
Wheel: a set of measures for clearer view in case of lots of weapons in a single slot:
- limit minimal angle between wheel hands;
- draw the selected weapon over other weapons in the second wheel;
- made wheel hands transparent in the middle.
