Mishang Urban Construction

Updated following content:

• Glowing hung signs and glowing wall signs with customizable colors.
• Added more signs with custom colors, and optimized the source.
• Standing signs.
• Added information tooltip for sign block items.
• Road with bevel angle double or thick line.
• Set the texture of bar part of ice hung sign to blue ice.

Fixed following issues:

• Tinting a terracotta hung sign bar with a color tool converts it into a sign instead of sign bar.
• If an opaque sign block connects with a translucent sign, the opaque fase will be incorrectly invisible.
• Some wrong code in the hung sign models.
• Incorrect configuration of auto lines of road.
