* Forbid dropping loaded digtron crates (see #44)
This workaround forbids dropping the crates, so the servers should no
longer crash so often because of loaded digtron crates.
* Check for protection when taking crates
* Use updated awards API
* Fix dig/place incrementing
* Use awards.player() in crates
* Use new 'dig' incrementor for digtron packing
* Only initialize tables if they dont exist
* Fix typo
* Remove init function, use checks instead
* fix crate protection
all crates check area protection (minetest.is_protected)
protected crates check area and owner (even if not in protected area)
* separate check and action
* whitespace stuff
* another missing whitespace
* add suggestion from T4im
