broke options up into tiddler and twee blocks

overall better than the increasing mess of `FilePath -> String -> String`
args that were starting to clog the function types
made -p control if jquery or modernizr were loaded into the generated file

i don't know exactly how this works in Twine 1.4, but there's some kind of
switch, so this might as well repurpose the twee plugin switch since it
used to be an undocumented feature
updated VERSION string to mimic the Twine 1.4 version string format.
