echinus: Add recipes for echinus (a wm) and ourico (a panel for echinus).

* Added echinus-jlime.patch, which contains jlime-specific changes
  to the echinus window manager

* Added ourico-jlime.patch, which contains jlime-specific changes
  to the ourico panel.

* Added Makefiles for both echinus and ourico which add two additional
  defines, INCS and LIBS which are used for additional defines due to
  the way OE handles CFLAGS and LDFLAGS.
