* WIP: Introducing the LSCP shell: for now, providing color
  highlighting while typing (indicating correct part bold white,
  incorrect part red, and turning green when the command is
  complete. The shell application is implemented as thin client,
  that is the parser work is performed on sampler side and the
  shell application is just providing output formatting.
* Bumped version (1.0.0.svn28).
