Version 0.6 of Lily. Major changes include:

* Lists are now a built-in class. This took a considerable amount of effort,
  and there are still parts not fully completed (like a list of objects that
  refers to itself not deref-ing, no empty lists, and a few more). But the
  majority of it is stable. Also, these bugs were left in because they need
  things that will be coming soon (typecasting being the big one).
* Complex signatures now okay for methods. This allows methods to take and
  return other methods.
* Lists support subscript from, and subscript assign. If a subscript returns
  a method, that method can be called anonymously in the same line (ex:
  list_method[0](1, 2)
* failtest_main is a new runner that runs a batch of tests that are supposed
  to fail. This is to cover what sanity.ly can't.
* LARGE cleanup of nearly everything. This was because finding things was
  becoming a chore, and quite a few functions were undocumented (or had wrong
  info).
* Finally added * and /, as well as *= and /=.
