Changed implementation of StartGDialogFix, additionally fixed the game crash if calling start_gdialog function outside of talk_p_proc procedure for talking heads.

Fixed "Heave Ho!" perk increasing strength stat above 10 when determining the max range of thrown weapons.
Moved SpecialUnarmedAttacksFix to BugFixes.cpp and simplified the code.
Added comments to old ApplyHeaveHoFix in Perks.cpp.
Backported some non-hook related script functions from 4.0: item_weight, get/set_outline, get/set_flags, tile_refresh_display, outlined_object, get/set_cursor_mode, display_stats, get/set_map_enter_position, attack_is_aimed.
