only write out upgrades list for worksites when upgrades are not empty,
partial fix for server crash issues
clean up reading of worksite tags to accomodate buggy vanilla JSON
int-array parsing (parses as nbt-list instead of nbtintarray).
add default setting of work bounds for bounded worksite tile when loaded
from disk.  Should resolve issues of crashing on the server
add more explicit error handling when constructing a template w/ instant
construction.
hack around issue of loading byte-arrays for worksite user-blocks,
should allow server to start + load.  need to rewrite template tag
parsing...again...
add .70 build
