* Fix truncation warning in `entrance.h`. * Fix type warning in fishsanity.cpp * Fix implicit conversion warnings in BossRush, Mouse, and UIWidgets.hpp. * Add Random_Float and use it in GameInteractor_RawAction.cpp. Make non-specified seed init a separate function. * clang after type change * Fix truncation and conversion warnings in ExtraTraps.cpp. * Resolve type conversion warnings in InputViewer.cpp. * Resolve some type conversion warnings in hook_handlers.cpp. * Remove `Random_Float`, and apply `RandomDouble` where it was being used instead. Add proper range notation to `RandomDouble` to denote the lack of inclusivity for the max part of the range. * Convert c-style casts to static_cast.
