Railroadways

Additions and Improvements:

• New Lighted Railroad Crossing Gate (two lights alternate continuously, and the third one always stays on when the gate is powered); acts just like the classic style crossing gate
• US-style lights and lighted gate (and the cantilevers) have new BlockEntity parameter "flasher_tick_delay", which specifies how fast in 'ticks' the lights will alternate (e.g. 40 ticks = 40 ticks in-between a flash change)
• Fixed 2 E-Bells from being loud at far distances by changing their sound to mono and decreasing attenuation distance
• Renamed old crossing gate to "Railroad Crossing Gate (Classic Style)"

Some internal things were changed in preparation for newer MC versions, but shouldn't affect gameplay in this version.
