Fix give when <ItemName> maps to a BlocID:DataValue pair
Implements unsafe give and unsafe item commands
Fixes to unsafegive/item commands

Turns out that if you list a constant as the name of a table it doesn't magically replace it with its represented number. Whoops. Also corrected Info.lua command handlers.
Added Comments
Eliminate `SafeCommand` as a global variable
Changed to straight file storage for the item blacklist rather then an INI
Tightened up comment matching
Changed DataTagTable to a local function variable
Change comment style, blacklist table format
Now with end of line comment support!
Updated README.la with new commands

Forgot to include these earlier
