literator v0.4.0

For better modularity and convenience of use, separated project into several parts:

• Library:
  • Added autogenerated links definition list (#7)
  • Changed index building and moved index to the bottom of the document
  • Solved problem of nested comments (#4)
  • Abstracted parsing over particular language (#1); Added the most useful languages
  • Made everything more File-centric (instead of just Strings);
  • Merged literateFile/Dir into one File.literate() method;
• Sbt plugin:
  • Has docsMap key, for multiple mapping between srcs -> doc dirs
  • Has docsOutputDirs for adding them to cleanFiles
• Command line application:
  • So far very primitive application; planning to add some nice options and conscript cover.

Other changes:

• Changed organization in sbt and package prefix in code to laughedelic
• Now publishing everything to Bintray
