stash values in structure scanner gui before opening block or biome
selection GUIs
update skippables list to include PAMS blocks (thanks Mohawky for your
work putting this together)
add detailed exception/error message for if a template is loaded without
the proper plugins to support its rule-types.
block lookup should now also work for "tile." block-names, and 1.6 block
names (but vanilla 1.6 names won't be compatible with 1.7....)
add user-configurable target blocks section to config file.  Names
should be listed as the unlocalized block name (either the 'tile.' or
non-tile variation).
