simplified set.rb
mods defining to format modules
got alias_view roughly working and added some Card::Set documentation
added API for aborting entire action via subcard
reworked subformat to create new format objects rather than cloning old ones
merged all the new dev setup and subformat stuff (and more) into superformat
new format loading mechanism largely working
Card no longer extended with Set
a few clarifying comments
got rid of all method_key references
got rid of opt_keys and opt_vals
whitespace cleanup
significant cleanup of "set patterns" and better handling of module loading
alias_view now working with blocks
minor cleanup re new view aliasing
got rid of terrifically annoying puts message
resolved merge conflicts between abort and superformat branches
