Added: orx templates + keywords, generix, mklib instant makefiles. Fixed: Installation rules.

- Fixed bug in Makefile install rulw (link was for my-scripts2 not lsd-tools2)
- Added generix (v1), README is still empty. See generix/examples for sample code.
- Added legacy/: lsdtools.shlib and  stx (specifically for generix support)
- mklib instant make files (not completely reusable yet):
  - cxx-generic.mklib: a generic makefile for small C++ projects, supporting org notebooks.
  - sync-to-sdcard.mklib: Syncing documentation/media from stage to sd card.
- Fixed install rules for orx/ => Install/link to ~/.orx/orx, also link orx/boilerplate to
  ~/.boilerplate
- Various orx templates.
- keyword-faces.el: Color definition for orx keywords.
- keywords.org: Keyword definition for orx processes.
