rewrote block queue handlers to reduce code duplication
and improve lag management minetest.conf settings added: biome_lib_dtime_limit: Maximum lag allowed, in seconds. Default 0.5s. Larger values allow for more lag, but make map updates run a bit faster. biome_lib_queue_run_ratio: If positive, this is the approximate number of globalstep ticks to skip between map updates. If negative, it becomes the positive number of map updates to run per globalstep tick before lag is checked. No minimum value, maximum +100. Default: -100 (that is, 100 updates per globalstep tick, with none intentionally skipped). Use positive numbers for slow machines or biome_lib-using mods that tend to cause lag, and negative values for fast machines and mods.
